A solution of benzene (C6H6) and toluene (C7H8) is 29.0 % benzene by mass. The vapor pressures of pure benzene and pure toluene at 25∘C are 94.2 and 28.4 torr, respectively. Assuming ideal behavior, calculate the total vapor pressure above the solution. Express the pressure to three significant figures and include the appropriate units.

Vapor pressures of benzene and toluene
Benzene and toluene form nearly ideal solutions. Consider an equimolar solution of benzene and toluene. At 20°C the vapour pressures of pure benzene and toluene are9.9 kPa and 2.9 kPa, respectively. The solution is boiled by reducing the external pressure below the vapour pressure.Calculate:(a) The pressure when boiling begins,(b) The composition of each component in the vapour, and(c) The vapour pressure when only a few drops of liquid remain
