A nonvolatile, non-dissociating solute was dissolved in 12.0 g of benzene (C6H6). The freezing point of the solution was measured as 1.3 °C, while pure benzene freezes at 5.5 °C. If pure benzene has a vapor pressure of 75 torr, what is the vapor pressure of this solution. For benzene, Kf = 5.12 °C/m and Kb = 2.53 °C/m.
