How do I design an experiment to find the number of H2O molecules in hydrated copper sulfate??

I know that the formula is CuSO4 5H2O ---%26gt; CuSO4 + 5H2O, but I need to design an experiment to prove it.

How do I design an experiment to find the number of H2O molecules in hydrated copper sulfate??
Take a known mass of copper(II) sulfate pentahydrate and weigh it. Then heat it until all the water evaporates and weigh it again.





Subtract the initial weight from the final weight and you get the weight of the evaporated water.





Then use stoichiometry to convert the mass of the water evaporated to moles of the water evaporated.





Figure out the moles of copper(II) sulfate from the weight of the anhydrous copper(II) sulfate and then use stoichiometry to see if the mass of the copper(II) sulfate and the mass of the evaporated water corresponds with that equation.
