1/27 Chemistry class and homework due 2/3

Hi folks,

Today we went over the method for determining the empirical formula and molecular formula of a compound. We also did a lab today were we tried to balance limiting reagents as we made the perfect batch of silly putty using water, glue and Borax.

Homework due next week is to:

1. Figure out (if you haven't already in class) how much water, borax and glue you would need to create 1000g of silly putty with nothing left over.

2. Using the masses you found in class, calculate how many moles of materials you used to create your "perfect" silly putty. The formulas for Borax and glue are on the sheets you received in class. Borax has a very strange formula with a 10H2O thing tacked to it. That's what happens when it combines with water.

3. Do problems 1-10 in the enclosed .pdf. Please be sure to check your answers.
