Question

Give reasons for the following :

Measurement of osmotic pressure method is preferred for the determination of molar masses of macromolecules such as proteins and polymers.

Answer

Protein is the high molecular mass material the magnitude of colligative property depends inversely on the molecular mass and osmotic pressure.

Osmotic pressure is fine at room temp, no special arrangements are required and it depends on molarity whereas all other colligative properties depend on molality.
