The freezing point of 48.06 g of a pure solvent is measured to be 45.44 ºC. When 2.04 g of an unknown solute (assume the van 't Hoff factor = 1.0000) is added to the solvent the freezing point is measured to be 43.09 ºC. If the freezing point depression constant of the pure solvent is 7.95 ºC·kg solvent/mol solute calculate the molar mass of the solute.
