Separate and Condense Condensed vapor YB1 = 0.714 The vapor pressure of pure benzene is 750.0 torr and the vapor pressure of toluene is 300.0 torr at a certain temperature. You make a solution by pouring "some" benzene with "some" toluene. You then place this solution in a closed container and wait for the vapor to come into equilibrium with the solution. Next, you separate and condense this resulting vapor and find that its mole fraction of benzene is equal...
