9.2 A solution of benzene (C6H6) and toluene (C7H8) is 22.0 % 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 vapor pressure of toluene in the mixture.

Express the pressure to three significant figures and include the appropriate units.
