A gas \(X\) is dissolved in water at 2 bar pressure. Its mole fraction in the solution is 0.02 . Find the mole fraction of water in the solution when the pressure of the gas is doubled at the same temperature.
- A 0.04
- B 0.98
- C 0.96
- D 0.02
Answer & Solution
Correct Answer
(A) 0.04
Step-by-step Solution
Detailed explanation
Pressure, \(p=2\) bar Mole fraction, \[ \begin{aligned} & \chi=0.02 \\ & p=K_{\mathrm{H}} \times \chi (Henry law)\\ & 2=K_{\mathrm{H}} \times 0.02...(i) \end{aligned} \] Pressure doubled.…
