JEE Main Chemistry question

For determination of molar mass of colloids, polymers and protein, which property is used? [OJEE 2004]

(A)Diffusion pressure
(B)Atmospheric pressure
(C)Osmotic pressureCorrect
(D)Turgor pressure

Answer: (C)

Solution

Osmotic pressure is especially suited to determine the molar mass of macromolecules (colloids, polymers, proteins) because even a very small molar concentration of such a large molecule produces a conveniently
