13.67) At63.5"C, the vapor pressure of H,O is 23.3 kPa, and that of ethanol (C2H,OH) is 53.3 kPa. A solution is made by mix- ing equal masses of H2O and C2H;OH. (a) What is the mole fraction of ethanol in the solution? (b) Assuming ideal- solution behavior, what is the vapor pressure of the solu- tion at 63.5 C? (c) What is the mole fraction of ethanol in the vapor above the solution?
