CuSO4 + X h20 -> CuSO4 +xH20 ...

a 9.6 g sample of CuSO4 was allowed to absorb water. After absorption the sample weighed 15.01 grams. What is the value of x?

    g H2O = 15.01-9.6 = ??
    moles water = grams/molar mass H2O.
    moles CuSO4 = grams/molar mass.
    Divide moles CuSO4 by itself (which gives you 1.000), then divide moles H2O by the same number. That will be X.
