A gas ' X ' is dissolved in water at 2 bar pressure. Its mole fraction is 0.02 in solution. The mole fraction of water when the pressure of gas is doubled at the same temperature is

Options

  1. A0.04
  2. B0.98
  3. C0.96
  4. D0.02

Correct answer

C. 0.96

Step-by-step solution

From Henry's law, if we increase the pressure then the mole fraction of gas in the water will increase by the same multiple. Hence, mole fraction of gas =0.04 . Mole fraction of water =0.96
