An online study examined the lowering of freezing point when 0.222 g of an unknown molecular solute was dissolved in 11.45 g of cyclohexane. The freezing point of pure cyclohexane was 6.6oC and the freezing point of the solution of the unknown was 3.3oC. The freezing point lowering constant, Kf, for cyclohexane is 20.0oC*(kg/mol). What is the molar mass of the unknown in g/mol? Enter your answer without units.
