For getting accurate value of molar mass of a solute by osmotic pressure measurement

Question

For getting accurate value of molar mass of a solute by osmotic pressure measurement (A) the solute must be volatile (B) the solution concentration must be high (C) the solute should undergo dissociation (D) the solute must be non-volatile

Tardigrade Admin · Accepted Answer

By osmotic pressure method, the molar mass of a non-volatile, non-electrolyte ( ie, neither undergoes association nor dissociation) solute is measured accurately.

Q. For getting accurate value of molar mass of a solute by osmotic pressure measurement

the solute must be volatile

the solution concentration must be high

the solute should undergo dissociation

the solute must be non-volatile

By osmotic pressure method, the molar mass of a non-volatile, non-electrolyte ( ie, neither undergoes association nor dissociation) solute is measured accurately.
