Chemistry 11-14 and 15-17 Moles, Mass, Atoms & Avogadro

CHEMISTRY: So… how big a bucket do you think we’d need to hold a mole of frogs? 🙂

Nope, not the furry brown creature that burrows underground, it’s a whole different thing! Here’s the lecture from Wednesday on moles, mass, and Avogadro’s number. Below that is our look at a couple of the homework problems with moles. I still say he has a cool name…

  1. This week I would rate myself a 3/5. I did not do well on my pretest and a lot of the errors came from small mistakes. In order to do well on the test I need to practice a lot more.

  2. This week in chemistry I rate myself a 2/5. I did very bad on my pretest because I have a hard time with naming chemical formulas, and I will need some more practice before the test on that area.

  3. I rate myself a 4/5 this week. I did really well on my pretest and understand everything we learned pretty well. I hope I don’t forget everything over thanksgiving break!

  4. I struggled with my pre-test we had this week by putting ions on compounds and now I have gone over what I have missed and will retake the pre-test to make a better grade and restudy the ions and compounds to make sure I get a good grade on the retake of the pretest.

  5. I would rate myself a 3/5 this week because i did bad on the pre test but learned what i did wrong and figured out how to study for the next one.

  6. This week in chemistry I rate myself a 3.5/5. I was kinda disappointed in my pre-test grade, because I studied really hard for it…I mean I did well but could’ve done better. The lab this week was okay….it was cool, but very fast-paced. The math part of this chapter is definitely something I’ll have to work on. Overall, it was a satisfactory week.

  7. I would rate myself a 3/5 this week. I should have studied more for the pre-test but I understood what I did wrong when I was correcting it. I did all my homework and took notes but I need to work on the conversions.

  8. This week was a 4/5 for me. The lab was far from difficult, and I’m confident in my lab write up. As for the pre-test, it was for from bad but I still would not call it good. Writing formulas is something to definitely work on. The conversion factors for moles and molecules are something that I need to begin memorizing too.

  9. This week I rate myself a 4.5/5. I missed a day and that threw me off a little, but I did well on my pretest and have been able to keep my chemistry work on track. I’m going to strive to be like this every week (minus the missing a day part)

  10. This week in chemistry I rate myself a 3/5. I was absent for the lab and I did not do that well on the pre-test. I completed all of my assignments that were due.

  11. This week I would rate myself 4/5. The iron tests lab was pretty stressful but I think we worked efficiently and diligently regardless of the 3 times we restarted. I accidentally procrastinated the lab write up and ended up doing it really fast and probably had a few careless errors. all in all, this week was good!!

  12. This week I would rate myself a 4/5 because the practice test at first I did not do very well, but then I took the new test and I think I did much better. The Tests for Iron Ions lab, I think I did good on and I am learning to manage my time a lot more than I have been.

  13. This week I would rate myself a 3/5. I did not prepare myself very well for the Pre-test we had this week. I hope that on the real test I will do better. I did good on my homework this week.

  14. I would rate myself a 3/5 this week because while I felt like I understood the material, I didn’t do that great on the pretest. Also, I waited until the last minute to start my lab write up.

  15. I rate myself a 3/5 this week. I should have prepared better for the pre-test. i think i did well on the retake. i also kept up with all my homework. I’m getting better at managing my time and listening in class.

  16. This week in Chemistry, I rate myself a 3/5. I did not do very well on the pre-test and got a little behind on my homework. However, I understood the lab and it was fairly easy. Also, I studied more and think I did better on the 2nd pre-test. Thankful for this week in Chemistry and have a happy thanksgiving!!

  17. This week I would rate myself a 2.5/5. I stuggled this week with understand all the problems and doing my homework. Hopefully when we get back it will become more clear to me.

  18. This week i rate myself a 3/5. I completed all of my HW this week and i took good notes. I’m still working on a good way to study.

  19. This week I would rate myself a 2/5. I took good notes this week and did well on the homework. But I didn’t do well on the pre-test and I need to work on my memorization.

  20. This week I rate myself a 3/5. This weeks homework was very difficult for me because I was very lost in the lessons. I could have studied harder for the pre test also.

  21. This week was a little different. I didn’t do as good as I hoped on the pre-test, so i just need to work a little more on memorization. I’m hoping after the break I will be able to absorb more information better! Overall i would rate myself 3/5 for this week.

  22. I would rate myself a 2/5 because I am having trouble understanding the homework, and I struggled to get my lab report done this week.

  23. I would rate myself a 3/5 this week because I didn’t do that well on the pre-test. I had to retake it and I hope I did better.And I think I get the molar mass stuff we learned.

  24. this week i rate myself a 4/5 i understood just about everything this week. the only thing i can say i struggled with this week would be the memorization. other than that i feel confident in what i learned this week

  25. I would rate myself a 3/5 for this week. I did not do that good on the first pre-test, but I feel that I did better on the second one. I also did good at taking notes and understanding the molar mass stuff.

  26. I would rate myself a 1.5/5 it was a bad week I don’t really get the calculating moles and molecules stuff the best yet and I did terrible on the first pre test the only positive is that I did all my homework and hopefully did well on the 2nd pre test

  27. I would rate myself a 3/5 this week. I did not do as well on the pretest as I thought I would, but I took the new pretest and think I did a bit better. I will have to study much harder for the actual test coming up if I want a more desirable grade.

  28. This week I would give myself a 2/5. I didn’t do very well on my pre-test at all, and didn’t have time to study for the make-up test. I spent longer than I should have working on the lab write-up, and forgot to do the book work on Thursday night. On top of that, I don’t believe that I took very good notes this week, but I still managed to understand the lesson. Next week I will try to do better with my time management.

  29. I rate myself a 4/5 this week because I didn’t do so well on my pre test but when I re took it today I felt more prepared for it.

  30. I would rate myself a 4/5 this week. I study for advance for the pretest and did real well on it. I think I could have done better on it if I would have study the common names substances. I took good notes this week and understood what we were going over. I feel like the pretest will help with the actual test.

  31. I rate myself a 2/5 this week. I say that because I did poorly on the pre test and didn’t study for it like I should have. I also had a really hard time learning the new material we started this week. Also, I don’t think I did as well as I wanted to on the brand new pre test today.

  32. I struggled a lot this week with the homework and all the problems! But i think I’ll be ok with the test and everything

  33. This week I would rate myself a 2/5, I did not do great at all on my pretest, and when I retook it I feel I made a lot of mistakes

  34. This week I would rate myself a 2/5, I did not do great at all on my pretest, and when I retook it I feel that I made many mistakes like on permanganate(MnO4)

  35. I would rate myself a 3/5 this week because I did absolutely horrible on the first pre test, but I do think I did better on the second one we took.

  36. I would rate myself a 3/5 this week because I did absolutely horrible on the first pre test, but I do think I did better on the second one we took. Hopefully after Thanksgiving I do better.

  37. I would rate myself a 3/5 this week because i did well on taking notes but i could have done much better on the pretest.

  38. This week I give myself 3/5. I struggled a little with the homework and was a little confused in class. I waited too late to start memorizing for the pretest and did pretty awful, but I think and hope I did much better on the new one, so thank you for letting us take a second one!

  39. I rate this week a 2/5. I did not do awful on the pretest, but it was not the grade I wanted. I also struggled a little with the math problems in the book work, but I believe that if I do more of those conversion problems, I will definitely understand it entirely.

  40. i️ rate myself a 4/5 this week. i️ did well on the pretest, even though i️ could have done better! the ones i️ missed were careless mistakes. i’m understanding the chapter we are in and i’m happy for a break.

  41. this week in chemistry i would rate myself a 3/5 i struggled mightly on the pretest because i missed all of last week. but i feel a lot better about the one i retook friday. i feel like i’m getting better at naming polyatomic ions. i did good with taking notes. i believe i will do good on the upcoming test.

  42. Something must have happened to my post as it is not showing up anymore, anyways probably won’t get credit but I digress. I rate myself a 4/5 this week. I did very well throughout the entirety of the week including a good grade on my pre test. I look forward to the rest of Thanksgiving break.
