    Which colligative property is preferred for the molar mass determination of macro molecules ? Why ?


    Osmotic pressure is preferred over all other colligative properties because :

    (a) even in dilute solution the osmotic pressure values are appreciably high and can be measured accurately.

    (b) Osmotic pressure can be measured at room temp. on the other hand elevation in B. P. is measured at high temp. where the solute may decompose. The depression in freezing point is measured at low temp.
