Question

Calculate the boiling point elevation of a solution made from 15.0 g of a nonelectrolyte solute and 250.0 g of water. the molar mass of the solute is 50.0 g and Kb = 0.51 degrees C/m

Answer 1

moles = grams/molar mass.
Calculate moles.

m = moles/kg solvent
Calculate m

delta T = Kb*m
calculate delta T.

Answer 2

thank you! i think the answer is 0.00612 is the delta t
