The partial molar volumes of water and ethanol in a solution with xH 2 O = 0.45
Question:
The partial molar volumes of water and ethanol in a solution with xH2O = 0.45 at 25°C are 17.0 and 57.5 cm3 mol–1, respectively. Calculate the volume change upon mixing sufficient ethanol with 3.75 mol of water to give this concentration. The densities of water and ethanol are 0.997 and 0.7893g cm−3, respectively, at this temperature.
