1-propanol (n-propanol), and 2-propanol (isopropanol), form ideal solutions in all proportions. Calculate the partial pressure of each component in equilibrium at 25 degree C with a solution of the following mole fractions; X_prop = 0.240, 0.480, and 0.720, given that P_prop = 20.9 Torr and P_Iso = 45.2 Torr at 25 degree C. Calculate the mole fractions (y) of the vapor phases as well.
