Directions : Read the passage given below and answer the following questions:

The properties of the solutions which depend only on the number of solute particles but not on the nature of the solute are called colligative properties. Relative lowering in vapour pressure is also an example of colligative properties.
For an experiment, sugar solution is prepared for which lowering in vapour pressure was found to be 0.061 mm of Hg. (Vapour pressure of water at 200C is 17.5 mm of Hg).

Colligative Properties and Relative Lowering of Vapour Pressure

What are Colligative Properties?

  • Properties of solutions that depend only on the number of solute particles but not on the nature of the solute are called colligative properties.

  • Examples of colligative properties are relative lowering of vapour pressure, boiling point elevation, freezing point depression, and osmotic pressure.



What is Relative Lowering of Vapour Pressure?

  • Relative lowering of vapour pressure (RLVP) is a colligative property that occurs when a solute is added to a solvent, which results in a decrease in the vapour pressure of the solvent.

  • The formula for RLVP is given by: RLVP = (P0 - P1) / P0, where P0 is the vapour pressure of the pure solvent, and P1 is the vapour pressure of the solution.



Solving the Question

  • The question states that a sugar solution was prepared, and the lowering in vapour pressure was found to be 0.061 mm of Hg.

  • The vapour pressure of water at 20°C is 17.5 mm of Hg.

  • Using the formula for RLVP, we can calculate the relative lowering of vapour pressure for the given solution:


    • RLVP = (P0 - P1) / P0

    • RLVP = (17.5 - 0.061) / 17.5

    • RLVP = 0.00348


  • Therefore, the relative lowering of vapour pressure for the given solution is 0.00348.



Answer
The correct answer is option A, which is 0.00348.
