When a solution is made from 47.8 g of an unknown nonelectrolyte dissolved in 151.4 g of solvent, the solution boils at 111.15 °C. The boiling point of the pure solvent and its K, are 108.91 °C and 5.01 °C/m, respectively. Calculate the molar mass of the unknown nonelectrolyte in g/mol. Report your answer to TWO places past the decimal.
