P9.20 The partial molar volumes of water and ethanol = 0.45 at 25C are 17.0 and in a solution with XHO 57.0 cm mol, respectively. Calculate the volume change upon mixing sufficient ethanol with 4.50 mol of water to give this concentration. The densities of water and ethanol are 0.997 and 0.7893 g cm, respectively, at this temperature.
