Is your answer in units of g/mol and not kg/mol? Did you subtract the new freezing point from the pure freezing point, and not the other way around? A solution of 27.25 g of an unknown nondissociating compound dissolved in 200.0 g of benzene freezes at 3.51 °C. Calculate the molecular mass of the unknown. Molar mass = g/mol Use correct number of significant digits;
