What is the weight in grams of 3.36*10^23 molecules of copper sulfate

According to Avogadro's law, 1 mole, i. e., 6.2 * 10^23 particles of every substance have mass equal to its molecular mass in grams. Since the molecular mass of CuSO4 is 80 grams. It means 6.2 * 10^23 particles of CuSO4 have a mass of 80 grams. Now u can calculate the mass of 3.36 * 10^23 particles by unitary method 3.36 * 10^23 * 80/6.23 * 10^23 grams
