A)calculate the molar mass of silver chloride
B)calculate the molar mass of copper(II)chloride
C)calculate moles silver chloride from precipitate mass
D)calculate the moles copper(II)chloride with the mole to mole ratios silver chloride : chloride and chloride : copper(II)chloride
E)divide moles copper(II)chloride by volume of the copper(II)chloride solution expressed in liters

To calculate the molarity of the copper(II) chloride solution, you don't need the molar mass of copper(II) chloride itself. You need the molar mass of silver chloride to find the moles of silver chloride precipitated, which can then be used to find the moles of copper(II) chloride through stoichiometry, and finally, the molarity of the copper(II) chloride solution by dividing by the volume of the solution.
