An ideal solution at 298 K is made up of the volatile liquids A and B, for which the vapor pressures at that temperature (when pure) are PAÂº = 125 Torr and PBÂº = 46.3 Torr. As the pressure is reduced from 450 Torr the first vapor (first bubble) is observed at a pressure of 70.0 Torr. What is the mole fraction of A in the liquid mixture?

A solution contains liquids A and B, at 25ËC, where the mole fraction of B is 0.600. The vapor pressures of pure liquid A and B at 25ËC are 153.5 and 400.0 torr, respectively. Assume ideality and determine the following:

The partial pressure of A above the solution = torr.

The partial pressure of B above the solution = torr.

The vapor pressure of the solution = torr

Mole fraction of B in the vapor =
