HW 11 itivities and Due Dates HW 11 re: 62.3% Resources Biphenyl, CiH, is a nonvolatile, nonionizing solute that is soluble in benzene, C.H. At 25 °C, the vapor pressure of pure benzene is 100.84 Torr. What is the vapor pressure of a solution made from dissolving 16.2 g of biphenyl in 32.8 g of benzene? Psolutie
