Sample Breakdown: Solving a Typical NCERT Question in Physical Chemistry

Question: Calculate the molar mass of a gas if its vapor pressure at 25°C is 200 mm Hg and the vapor pressure of pure water at the same temperature is 23.8 mm Hg. Assume the gas obeys Dalton’s law of partial pressures.

Solution Approach:

1. Identify knowns:

• Vapor pressure of the gas, P_gas = 200 mm Hg
• Vapor pressure of water, P_water = 23.8 mm Hg
• Temperature, T = 25°C = 298 K

2. Use Dalton’s Law:

• Total pressure, P_total = P_gas + P_water

3. Calculate the partial pressure of the gas:

• P_gas = 200 mm Hg

4. Apply ideal gas law:

• PV = nRT
• Molar mass M = (mass / moles)

5. Determine the number of moles (assuming 1 g sample):

• Use the relation:

\( P \times V = \frac{m}{M} \times R \times T \)

6. Rearranged to find M:

• M = (mass × R × T) / (P × V)

7. Plug in the values:

• R = 0.0821 L·atm/(mol·K)
• Convert pressure to atm: 200 mm Hg = 200/760 ≈ 0.263 atm
• Assume V = 1 L for simplicity

8. Calculate M:

• M = (1 g × 0.0821 × 298) / (0.263 × 1) ≈ 93 g/mol

Final Answer: The molar mass of the gas is approximately 93 g/mol.

This step-by-step approach exemplifies how NCERT solutions break down complex problems for clarity.
