CHEMISTRY – So you think Goodman Road is 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.
- 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 tomorrow. Speaking of tomorrow, any questions about the thLAB: SI Scavenger Hunt? Bring your questions tomorrow and I’ll be glad to help!
