Final answer:
The boiling point elevation is a colligative property that can be used to determine the molar mass of the solute.
Step-by-step explanation:
The boiling point elevation is a colligative property that is related to the molality of the solution. It is the difference in temperature between the boiling point of the pure solvent and that of the solution. We can use the equation ΔT = Kb × m to determine the molar mass of the solute, where ΔT is the boiling point elevation, Kb is the molal boiling-point elevation constant, and m is the molality of the solution.
