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

Options

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

Answer

A

Explanation

Osmotic pressure is a colligative property which is used to find the molecular weight of polymer because other colligative properties given so low value of molecular weight that it cannot be measured accurately.
