You are given a solution of anthracene (a non-electrolyte solute, 178.23 g/mol) in benzene (78.11 g/mol, C6H6). The freezing point of this solution is 0.00oC. What is the vapor pressure (torr) of this solution, if anthracene has no vapor pressure (in other words, if anthracene is non-volatile)? For grading purposes, please report the calculated pressure to 3 significant figures. For pure benzene: vapor pressure at 25oC equal 97.7 torr; freezing point is 5.51oC, and Kf = 5.12oC/m. Hint: Assume 1 kg solvent. How is total vapor pressure related to mole fraction?
