Assuming this is a bone-dry sample, we are talking only of the water of hydration. You have 5 times the molecular weight of water divided by the weight of the entire hydrated molecule, which is the molecular weight of copper sulfate plus 5 times the molecular weight of water.

Roughly, 90 / (250 + 90), or 26%

By performing a hydrate analysis of copper sulfate, you will find that the percentage of water in hydrated copper sulfate is 36%.
