An ideal solution of toluene (vapor pressure 21 torr) and cyclohexane (vapor pressure 67 torr) in which the mole fraction of cyclohexane is 0.74 is boiled and the vapor condensed to a liquid. What is the mole fraction of cyclohexane in the condensed liquid?
I can't figure this darn thing out... I always thought that the mole fraction of a solution (regarding phase) is the same no matter what... So I thought the answer would be 0.74 and its not....
Can anyone help plz
