Which property is used for determination of molar mass of colloids, polymers and proteins

Mention three specific conditions necessary for the determination of correct molar mass of a solute by studying colligative properties of its solution.

Suppose you are required to determine the molecular mass of a protein molecule. Which colligative property is suitable for this purpose? Write the necessary equation for the determination of molecular mass.

The molecular mass of sodium chloride obtained by using a colligative property is
