    Molar mass of CuSO4*5H2O = 63.5 + 32 + 4 (16) + 5 (18) = 249.5 g/mole

    molarity is calculated as follows:

    molarity = number of moles of solutes/liters of solution

    We will assume that the number of liters = 1

    Substituting in the above equation:

    0.02 = number of moles of CuSO4*5H2O / 1

    number of moles = 0.02 moles

    number of moles = mass/molar mass

    mass = number of moles * molar mass

    mass = 0.02 * 249.5 = 4.99 grams
