Biphenyl, $C_{12}{H}_{10},$ is a nonvolatile, nonionizing solute that is soluble in benzene, $C_6{H}_6.$

At $25C,$ the vapor pressure of pure benzene is $100\mathrm{.}84$ Torr. What is the vapor pressure of a solution made from dissolving $16\mathrm{.}5g$ of biphenyl in $26\mathrm{.}7g$ of benzene?
