Chemistry 9-3-19 Using Density & Conversion Factors

CHEMISTRY – Hey guys, here’s a pic of some “high density” koi that I saw in Hawaii (at the Dole Pineapple Plantation, of all places!). Great review on density 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 learned this week about conversions and the equation for volume and the Q formula. it’s been a little rocky, but we are getting there.

  2. I learned a new formula that I have never heard of and that I never knew existed. It is hard to master but easy to use once you get the hang of it.
