MHT CET Chemistry question

Which of the following colligative properties can provide molar mass of proteins (or polymers or colloids) with greater precision ?

(A)Relative lowering of vapour pressure
(B)Elevation of boiling point
(C)Depression in freezing point
(D)Osmotic pressureCorrect

Answer: (D)

Solution

For very large molar masses the solution is extremely dilute, so lowering of vapour pressure, elevation of boiling point and depression of freezing point
