The freezing point depression of a solution made by the addition of a nonionic unknown solute to benzophenone was used to determine the molar mass of the unknown. Data was collected for a solution containing 500. g of benzophenone with 5.0 ml of the unknown solute added. The density of the unknown solute was 6.18 g/ml. The K_f of benzophenone is 9.8 degree C M^-1. The freezing point of the benzophenone was determined to be 7.19 degree C. The freezing...
