The vapor pressure of benzene is 73.03 mm Hg at 25 °C. A nonvolatile, nonelectrolyte that dissolves in benzene is cholesterol.
Calculate the vapor pressure of the solution at 25 °C when 8.278 grams of cholesterol, C27H46O (386.6 g/mol) are dissolved in 222.4 grams of benzene.
benzene = C6H6 = 78.12 g/mol
VP(solution) = ____ mHg
