Molar masses of salutes are best measure...

Molar masses of salutes are best measured from osmetic pressure. Why?

Text Solution

Verified by Experts

Compared to other colligative properties of magnitude of osmotic pressure is large even for very dilute solution. Determination of molar masses is particularly useful for polymers as they have poor solubility and biomolecules as they are unstable at higher temperatures.
