Osmotic pressure

Vedclass · Answer

(A) Polymers have very high molar masses,which results in very low values for properties like relative lowering of vapour pressure,elevation in boiling point,and depression in freezing point. These small changes are difficult to measure accurately. Osmotic pressure $(\pi)$ is the most suitable colligative property for determining the molar mass of polymers because it involves a measurable magnitude even for very dilute solutions. The formula used is $\pi = CRT = (n/V)RT = (w/MV)RT$,where $M$ is the molar mass. Since $\pi$ is significant even at low concentrations,it provides more accurate results.

Which of the following colligative properties is most suitable for determining the molar mass of polymers?
