Question

What mass of glycerin (C3H8O3), a nonelectrolyte, must be dissolved in 400.0 g water in order to give a solution with a boiling point of 103.50 C?

Answer 1

delta T = Kb*m
Solve for molality = m

m = mols/kg solvent
Solve for mols.

mols = grams/molar mass. You know mols and molar mass, solve for grams.
