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
$0.04$
$0.98$
$0.96$
$0.02$
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 $=0.96$
