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).

**Answer:**
The vapour pressure of a solution can be determined using Raoult's law, which states that the partial pressure of a component in a solution is directly proportional to its mole fraction. In this case, the solute is sugar and the solvent is water.
Given:
- Lowering in vapour pressure = 0.061 mm of Hg
- Vapour pressure of water at 20°C = 17.5 mm of Hg
**Calculating the mole fraction of sugar:**
Let's assume that the mole fraction of sugar in the solution is represented by x.
Since the vapour pressure of the solution is lower than that of pure water, the mole fraction of sugar must be less than 1.
According to Raoult's law, the vapour pressure of the solution can be calculated as follows:
Vapour pressure of solution = mole fraction of sugar * vapour pressure of pure water
0.061 mm of Hg = x * 17.5 mm of Hg
Solving for x, we get:
x = 0.061 / 17.5
x ≈ 0.00348
**Calculating the vapour pressure of the solution:**
The vapour pressure of the solution can now be determined by substituting the mole fraction of sugar into Raoult's law:
Vapour pressure of solution = 0.00348 * 17.5 mm of Hg
Vapour pressure of solution ≈ 0.061 mm of Hg
Therefore, the vapour pressure of the solution is approximately 0.061 mm of Hg.
**Conclusion:**
The correct answer is option C, 17.439 mm of Hg.

0.061 mm of Hg = x * 17.5 mm of Hg
Solving for x, we get:
x = 0.061 / 17.5
x ≈ 0.00348
**Calculating the vapour pressure of the solution:**
The vapour pressure of the solution can now be determined by substituting the mole fraction of sugar into Raoult's law:
Vapour pressure of solution = 0.00348 * 17.5 mm of Hg
Vapour pressure of solution ≈ 0.061 mm of Hg
Therefore, the vapour pressure of the solution is approximately 0.061 mm of Hg.
**Conclusion:**
The correct answer is option C, 17.439 mm of Hg.

To find the correct answer, we need to calculate the vapor pressure of the sugar solution. The vapor pressure lowering is given as 0.061 mm of Hg, and the vapor pressure of pure water at 20°C is 17.5 mm of Hg.
The formula to calculate the vapor pressure of the solution is:
\[ \text{Vapor pressure of solution} = \text{Vapor pressure of pure solvent} - \text{Lowering in vapor pressure} \]
Substituting the given values:
\[ \text{Vapor pressure of solution} = 17.5 \, \text{mm of Hg} - 0.061 \, \text{mm of Hg} \]
\[ \text{Vapor pressure of solution} = 17.439 \, \text{mm of Hg} \]
\[ \text{Vapor pressure of solution} = 17.439 \, \text{mm of Hg} \]
Therefore, the correct answer is:
3) 17.439
