The densities of aqueous solutions of copper (II) sulfate at 20 C were measured as set out below. a. Plot the mol of CUSO4 versus volume of the solution in the range of the measurements. b. Determine the partial molar volume of CuSO4 for 1 mol of CuSO4 in solution. m CuSO4 (g) p (g/cm') 52.6 1.051 111 1.107 176.5 1.167 250 1.230 where m(CUSO4) is the mass of CUSO4 dissolved in 1000 g of water. MW(CuSO4)=159.6 g/mol
