Asked by John
A solvent has a molar mass of 37.2 g/mol and a normal boiling point
of 111.2 oC. The boiling point elevation constant, K b , for this solvent
is 1.58 oC/m. If 18.7 g of a nonelectrolyte having a molar mass of
20.5 g/mol are mixed with 170.0 g of the solvent, what is the boiling
point of the solution?

mols solute = grams/molar mass
Solve for mols
molality = mols/kg solvent
Solve for m
delta T = Kb*m
Solve for dT and add to normal boiling point.
