Which of the following colligative properties can provide molar mass of proteins, polymers and colloids with greater precision?

Options

  1. AElevation in boiling point
  2. BDepression in freezing point
  3. COsmotic pressure
  4. DRelative lowering of vapour pressure

Correct answer

C. Osmotic pressure

Step-by-step solution

Among the given colligative properties, osmotic pressure can provide molar mass of protcins, polymers and colloids with greater precision. Because for these substances, the value of other given colligative properties are too small to be measured. Secondly, this method has the advantage i.c., this use molarities instead of molalities.
