Text Solution

Verified by Experts

The correct answer is:

Elevation in boiling point and depression in freezing point are colligative properties because they depend only on the number of solute particles in a solution irrespective of their nature. But all colligative properties are not used for mass determination for every substance, as some of them looks precision, or require excessive heating or cooling.
