A solution contains 0.180 g of an unknown nonelectrolyte solute in 50.0 g of water. The solution freezes at –0.040 0C (notice the negative sign).

A) What is the molar mass of the unknown solute?

B) What is the boiling temperature of the solution?

Kf(water) = 1.86 K kg mol-1   ;   Kb(water) = 0.51 K kg mol-1   . Assume that the solute only exists as a monomer in aqueous solution.
