Osmotic pressure

Vedclass · Answer

(C) Measurement of osmotic pressure is the most suitable method for determining the molar masses of polymers. $1$. Polymers and proteins are large macromolecules that have low solubility and are often unstable at higher temperatures. $2$. Osmotic pressure measurements are performed at room temperature,which prevents the degradation of these sensitive molecules. $3$. The magnitude of osmotic pressure is significantly larger than other colligative properties even for very dilute solutions,making it easier to measure accurately. $4$. It uses molarity $(M)$ instead of molality $(m)$,which is more convenient for these types of solutes.
