At 63.5 C the vapor pressure of H2O is 175 torr and that of ethanol is 400 torr. A solution is made by adding equal masses of H2O and C2H5OH. What is the mole fraction of ethanol in this solution? Sdduming ideal-solution behavior, what is the vapor pressure of the solution at 63.5 C? What is the mole fraction of ethanol in the vapor above the solution?
