gravi experiment

[Nomvalt]

If you wanted to determine the percentage of water in a sample of crystals of hydrated copper(II) sulfate by gravimetric analysis would it be sufficient to only weigh out the crystals before analysis using the electronic balance and then putting it into an oven and then weighing them again? Stoichiometry would be used next to determine the percentage of water in the sample. I am supposed to design a simple experiment on how this can be achieved, but there's nothing more to it than that is there?

You must remember to heat TO CONSTANT MASS (i.e. reheating until there is no change in mass).
Other than that, that is all that is required.

Ok, thanks.
