Question

Which of the following colligative properties can provide molar mass of proteins (or polymers or colloids) with greatest precision? (A) osmotic pressure (B) elevation of boiling point (C) depression of freezing point (D) relative lowing of vapour pressure

Tardigrade Admin · Accepted Answer

Measurement of osmotic pressure provides a method to determine molar masses of solutes. This method is widely used to determine molar masses of proteins, polymers and other macromolecules.
