CuSO4 = 160.
CuSO4.5H2O = 250.
The 5 waters = 90.
So 90/250 x 100 is the percentage of water in the most common hydrate. Now you can work it out.

Kara, the first part seems rather simple. Just add up the molecular mass of each atom component in CuSO4
To calculate the hydrate, you first need to know how many moles of water are attached as the hydrate. If this is not given in your problem, look up the compound on google and see if there is a typical hydrate formula.
Then you can calulate the percentage of water in the grand total.
