The elevation in boiling point of a solution is proportional to the ______________ of the solution?
Correct answer: A. Molal concentration
- A. Molal concentration
- B. Reciprocal of the molal concentration
- C. Normality
- D. Molarity
Explanation
For a dilute solution, boiling-point elevation follows ΔTb = Kb m, so it is proportional to molality, the moles of solute per kilogram of solvent. Molarity and normality depend on solution volume and are not the defining concentration here.
