12.50 g of a hydrated form of copper(II) sulfate, CuSO4•x H2O (where x is unknown) is gently heated. When all the water has been driven off, the mass of the anhydrous copper(II) sulfate is found to be 7.99 g. What is the mass of the water that was lost as a result of the heating? Convert this mass of water to moles of water. Convert the mass of the anhydrous CuSO4 to moles. Divide the answer to b by the answer to c. This is the value of x in the formula of the hydrate. Write the formula of hydrated copper(II) sulfate.
