You dissolve 152.5 g of CuCl2 in water to make a solution with a volume of 2.25 L. What is it’s Molarity? Show your work

Because electrons have negligible mass, to account for the mass of the isotope, there must be 16 neutrons, 16 neutrally charged, massive, fundamental particles present in the sulfur nucleus. and thus finally, if we have the 32s2− ion, there are 18 electrons, 16 protons, and 16 neutrons.
