Benzene and toluene form essentially ideal solutions. A particular mixture that consists of two moles of benzene and three moles of toluene has a total vapor pressure of 280 mmHg at 60 degrees celcius. If one additional mole of benzene is added to the solution, the the new total vapor pressure is now 300 mmHg. Calculate the vapor pressure of pure benzene and toluene at 60 degrees celcius
