Chem Lab

in lab we did we had to pick a hydrate and follow the steps
1) we had to weight the empty dry test tube
2) we had to weight the test tube with the hydrate in it
3) we had to light the bunsen burner
4) we had to boil all the water out of the hydrate
5) once we boiled all the water out we had to weigh the hydrate again
6) we calculated how much grams of water was boiled off and how much percent of water the hydrate was
7) we had to calculate our percent error for the percentage of water boiled off
