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

A.Relative lowering to vapour pressure

B.Elevation of boiling point

C.Depression in freezing point

D.Osmotic pressure.✓ Correct

Explanation

Osmotic Pressure is widely used for the measurement of molecular weight of polymers or macromolecules. It provides the method through which molar mass of solute is determined with great precision.
