9) An ethanol-water solution is 40.00% ethanol by mass and has a density of 0.9450 (g/cm3) at 25.00°C. The density of pure ethanol is 0.7850 (g/cms) and the density of pure water is 0.9970(g/cms) at this temperature. At these conditions, the partial molar volume of ethanol is 55.00 (cm3/mol) and the partial molar volume of water is 17.5 (cmmol). a. Calculate the total volume of a 1000.0 g solution assuming both ideal and non-ideal conditions. b. What does the difference...
