At 25 deg C vapor pressure of liquid benzene is 95.2 mmHg while the liquid touluene has a vapor pressure of 28.4 mmHg. The 2 liquids are miscible, non-electrolytes and obey raults law. What is the vapor pressure of a solution consisting of 4 moles of benzene and 5 moles of toluene?What is the mole fraction of benzen in the vapor above the solution from the mixture?
