The first thing to do here is to use the molarity and the volume of the initial solution to figure out how many grams of copper(II) chloride it contains.133mL solution⋅1L103mL⋅7.90 moles CuCl21L solution=1.051 moles CuCl2To convert this to grams, use the compound's molar mass1.051moles CuCl2⋅134.45 g1mole CuCl2=141.31 g CuCl2Now, you know that the diluted solution must contain 4.49 g of copper(II) chloride. As you know, when you dilute a solution, you increase the amount of solvent while keeping the amount of solute constant.This means that you must figure out what volume of the initial solution will contain 4.49 g of copper(II) chloride, the solute.4.49g⋅133 mL solution141.32g=4.23 mL solution−−−−−−−−−−−−−− The answer is rounded to three sig figs.You can thus say that when you dilute 4.23 mL of 7.90 M copper(II) chloride solution to a total volume of 51.5 mL , you will have a solution that contains 4.49 g of copper(II) chloride.
