A certain liquid had a normal freezing point of -9.6 oC. Its freezing point depression constant, Kf, is 2.46 oC/m. A 1.200-L solution was prepared by dissolving 100.0 g of an unknown compound in the liquid mentioned above. This solution freezes at -14.47 oC. The density of the solution is 1.05 g/mL. Calculate the molar mass of the unknown compound.
