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 6.18 mol of water to give this concentration. The densities of water and ethanol are 0.997 and 0.7893 g cm−3, respectively, at this temperature.
