CORRECTION!!! on the latest practice sheet I just posted, for #3, the calculation for percent H in H2O should have used 2.02/18.02. this propagates through the whole problem. When you get to the empirical formula calculation you should be using 13.4g of H and the empirical formula should be:  C1H4N

Any others let me know. (a note on #2, I used the R value from the lab. Old habits die hard, I will try to use the IB R value from now on. you should get the same answer either way. A constant is a constant no mater what the units.)
