A researcher prepares a new compound and uses freezing point depression measurements to determine the molar mass of the compound. He dissolves 1.66 g compound in 75.00 g of cyclohexane. Cyclohexane has a freezing point of 6.50 °C and a freezing point depression constant of 20.2°C kg/mol. The freezing point of the solution is measured as 2.98°C. Calculate the molar mass of the new compound. Record your answer to 3 sig figs
