In order to find the molar mass of an unknown compound, a research scientist prepared a solution of 0.930 g of an unknown in 125 g of a solvent. The pure solvent had a freezing point of 74.2 degrees celcius, and the solution had a freezing point of 73.4 degrees celcius. Given the solvents freezing point depreesion contant, Kf=5.50 degrees celcius/m, find the molar mass of the unknown
