The partial molar volumes of water and ethanol in a solution with xH2O= 0.60 at 25 degrees celcuis are 17.0 and 57.0cm3/mol, respectively. Calculate the volume change upon mixing sufficient ethanol with 2.00mol of water to give this concentration. The densities of water and ethanol are 0.997 and 0.7893gcm-3, respectively, at this temperature.
