CHEMISTRY: So how many water molecules are in this drop? Here’s the lecture from today on formula mass and then using molar mass and Avogadro’s number as a conversion factor. You did a great job on thinking through the problems! Now go forth and practice them so you don’t forget!

gosh I hope I can do better now that we are doing more math. I pray.
These molar mass problems are kinda difficult but fun to learn 🙂
Will we go over our tests in class this week? Also, thanks for doing a bunch of problems with us today! That helps alot
Finally! Something I understand! Thank you for going over it with us. It makes me feel like I know what I’m doing. Thank you so much!
I really enjoy the molar mass problems.
Thank you for going over the homework it really helped me grasp the information.
I feel like i am really understanding things now.
I like going over problems in class! it really helps me.
I loved going over the problems with you in class – it helps me figure out how to do it at home by myself!
The lab today was fun and not hard!
The lab today was simple and fun!
I like how i can find how many moles are in my name using chalk
The chalk lab was SO fun! I love the simple and easy labs!
It’s really cool how scientists came to know the different parts of an atom without actually seeing it.
Writing my full name in chalk was an exciting and colorful lab!
This post really helped me understand better since I’ve been absent. And also the lab today was easy.
I really liked that we already kinda knew how to do the molecule problems without you showing us how to do it. It made me feel really smart!
The lab on Wednesday was very easy once I figured out exactly how you wanted us to work the problem.
Going over the problems in class that we did for homework, it really helps me
The chalk lab was pretty simple and I’m glad we went over the problems in class.
I liked the gum thing today it was a really nice flavor of class.
I really enjoyed the gum lab we did today it was fun and easy.
I liked the gum lab we did today. It was pretty cool and I didn’t know the gums mass changed that much after chewing it. I never thought of that.
I really enjoyed learning about the father’s of chemistry this week.
I really enjoyed the can-in-a-sock lab today.
I enjoyed the gum lab today.
I enjoyed the gum lab today!
Didn’t even notice the one right above mine…
I had fun doing the gum lab today! It made me realize how we can actually use the percentage composition formula in real life!
The chalk lab and the gum lab were really easy and fun to do this week!
The gum lab was fun today, I didn’t realize how drastically the mass changed after chewing it for a while.
I like going over the problems in class. it helps me understand how to work them better.
I enjoyed the lab we did this week. It was not hard once I figured out what to do.
I really enjoyed doing the labs this week. It really helped me to apply what I know.
I enjoyed the labs we did this week
