    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

    Correct Answer: D

    Solution :

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