what is the advantage of using osmotic pressure as compared to other colligative properties for the determination of molar masses of solutes in solutions?

 Osmotic pressure has advantages for finding out the molar mass over other collegative properties as pressure measurement is around room temperature and molarity is used instead of molality.

 As compared to the other collegative properties  its magnitude is large enough even for the dilute solution

  1.  Osmotic pressure can be determined at any (room)temperature,while others methods are carried out at high temp. .At high temp. denaturation of polymers occurs.So high temp cant be used.
  2. OP value depends on molarity of soln .So it has a significant value whileothers depend on molality.So deltaTf,delta Tb value calculated will be very very small for polymers
