The partial molar volumes of acetone (propanone) and chloroform

Question
(a) The partial molar volumes of acetone (propanone) and chloroform (trichloromethane) in a mixture in which the mole fraction of CHCl3 is 0.4693 are 74.166 cm3 mol−1 and 80.235 cm3 mol−1, respectively. What is the volume of a solution of mass 1.000 kg?

(b) The partial molar volumes of two liquids A and B in a mixture in which the mole fraction of A is 0.3713 are 188.2 cm3 mol−1 and 176.14 cm3 mol−1, respectively. The molar masses of A and B are 241.1 g mol−1 and 198.2 g mol−1. What is the volume of a solution of mass 1.000 kg?
