Which of the following physical properties is used to determine, the molecular mass of a polymer solution?
1 Relative lowering of vapour pressure
2 Elevation in boiling point
3 Depression in freezing point
4 Osmotic pressure
Explanation:
Best method to determine the molecular mass of colligative property is osmotic pressure

Assertion : Elevation in boiling point and depression in freezing point are colligative properties. Reason : All colligative properties are used for the calculation of molecular masses.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but Reason is correct.
Explanation:
Colligative properties like elevation in boiling point and depression in freezing point, dependent on solute particles, and all colligative Properties are used to measure molar mass. So option (2) is correct.

Which of the following is not a colligative property?
1 Elevation in boiling point
2 Depression in freezing point
3 Osmotic pressure
4 Lowering of vapour pressure
Explanation:
Relative lowering of vapour pressure is a colligative property. As, it depends only upon the no. of moles of the solute and solvent and is independent of nature of the solute.
