A 1.200 gram sample of C7H6O2 was dissolved in 11.42 grams of lauric acid, and it was determined that the freezing point of the lauric acid was lowered by 1.680 Celcius. The value of Kf of the lauric acid is 3.90 Celcius m^-1. Assume that the compound does not dissociate in lauric acid.
Calculate the molar mass of the C7H6O2 from the information provided.
