ConceptColligative Properties and Determination of Molar Mass - Depression of Freezing Point

#### Question

1.0 x10-3Kg of urea when dissolved in 0.0985 Kg of a solvent, decreases freezing point of the solvent by 0.211 k.

1.6x10 Kg of another non-electrolyte solute when dissolved in 0.086 Kg of the same solvent depresses the freezing point by 0.34 K. Calculate the molar mass of the

another solute. (Given molar mass of urea = 60)
