Determine the volume change upon mixing sufficient ethanol with the 2.00 mol of water to give this concentration. The partial molar volumes of ethanol and water in a solution with x(H20) = 0.60 at 25 C are 57.0 cm3mol -1 and 17.0, respectively. The densities of ethanol and water are 0.997 and0.7893 g cm-3, respectively, at this temperature.
