Evaluate the molar mass of the unknown

Reference no: EM13236658

When determining the molar mass of unknown liquid (non-electrolyte). The solution was made by mixing 0.961 g of the unknown with 100.0 g of water. The freezing point depression of the solution was ?3.7°C. Calculate the molar mass of the unknown. Assume that the molal freezing point depression constant of water is 1.86°C•kg/mol and that the freezing point of water is 0.00°C. Please show all calculations in solving the problem
