Describe how you could find the % by mass of water in the hydrate CuSO4Ÿ5H2O assuming that you

did not already know the formula. Be specific and list the laboratory procedural steps you would take

in the order that you would perform them.

What this question is looking for is a very detailed answer, the procedure to follow if you will, and no one here will write up a procedure for you. However, I can give you the basic steps and you and can add to it.

Weigh the sample, heat to drive off the water, and weigh again. The difference in weight is the amount of water lost. Then convert to percent.
