An ideal solution is made by mixing 107.5 grams of hexene (C6H12) and 128.5 grams of chloroform (CHCL3). If the vapor pressure of the pure liquids at 20.0deg C are 227 torrand 31.7 torr respectively, what will be the total vapor pressure of the mixture? Also, what will be the mole fraction of each compound in the vapor?
