The amount of a substance can be converted into grams of that substance by using the molar mass. It is a physical property of a substance which describes the mass per mole of the substance. The molar mass of CuSO4 is 159.61 g / mol. Multiplying the given amount of CuSO4 from multiplying with the Avogadro's number to yield number of moles with the molar mass will yield to the mass of the substance.

159.61 g / mol CuSO4 (3.36 * 10^23 molecules / 1 mol / 6.022 x 10^23 molecules) = 89.06 g CuSO4
