What is Determining Hydrated Salt Formula about?

The document describes an experiment to determine the formula of a hydrated salt, copper(II) sulfate pentahydrate (CuSO4·5H2O). The hydrated salt is heated to drive off water, then weighed to find the mass of water lost. Calculations determine there are 5 moles of water per mole of copper(II) sulfate. The process of losing water upon heating is exothermic as adding water back causes an increase in temperature.
