Chemistry 9-3-21 Using Density

CHEMISTRY – Great work with density today. Below is the lesson from today and below that is the help session from this morning.

Great review on density concepts and problems today, and more! Remember, in chemistry we use math as a tool, therefore we might work problems a little differently in chemistry than you do in your math class.

When working these problems, don’t forget to follow the problem solving steps we discussed today:

  • Analyze – write down what you’re given and what you’re looking for
  • Plan – write a formula where you isolate the unknown on one side by itself
  • Compute – plug in your data, numbers and units; then cancel the units, and if they cancel correctly, go on to the calculator. Be sure and give your answer what the correct units.
  • Evaluate – does your answer make sense, have you used the correct units, do you have the correct sig figs?

  1. I rate myself 5 stars on completing my chemistry lab today. I completed it on time and answered all of the questions. I also learned something new while doing the lab.

  2. I rate myself 5 stars for the homework the was due Tuesday. I got all the problems except one right and I understand what I did wrong on the problem that I missed and how to fix it. I now feel more confident for all the Q formula questions on the test.
