CHEMISTRY – So you thought Goodman Road was getting crowded! How’s this for a “high density” city? Great job on the density problems today! 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. And finally, evaluate – does your answer make sense, have you used the correct units, do you have the correct sig figs? Wait – scratch that last thing, we’ll do sig figs in a couple of days.

And who knew raisins could dance! I think you’ve done a lot of this already, but make sure you understand the conceptual side of density as well – that’s a hint for your conclusion!

Wow! I would not want to live there! Thank you for working the density problems out in class today, really helped on my homework! Also, the dancing raisins lab was fun today! π

Thank you for showing us how to receive full credit on math problems!

Glad we went over the homework in class today it helped me alot. Thanks!

I’m glad we went over the homework problems. It helped alot!

Can anyone tell me what the standard SI unit for density is?

The SI Unit for density is kilograms per cubic meter.

density is cool
