In this experiment students will measure the mass of hydrated copper(II) sulfate before and after heating and use mole calculations to find the formula.

This is a class experiment suitable for students who already have a reasonable understanding of the mole concept. Given adequate access to top-pan balances, and skill in their use, students should be able to complete the experimental work in 30–40 minutes.
