Question

Why is boiling-point elevation a colligative property?

A. It does not depend on a molal boiling-point constant for each solvent.

B. It is independent of changes in vapor pressure.

C.It is directly proportional to the molal concentration of a solution.

D.it is inversely proportional to the molal concentration of a solution.

Answer 1

the answer is option C

Step-by-step explanation:

Boiling point elevation is a colligative property of matter, i.e. it is dependent on the solute-to-solvent ratio but not on the solute's identity. This implies that the elevation in the boiling point of a solution depends on the amount of solute added to it
