p=KH X where p arrow Partial pressure of gas X2 arrow Mole fraction of gas in solution KH= Henry's law constant So, p propto solubility (p1/p2)= (s1/s2) ⇒ (500/0 . 01)= (750/x) ∴ x=0.015 g/L

Q. The solubility of $N_{2}$ in water at $300 K$ and $500 torr$ partial pressure is $0.01 g L^{- 1} .$ The solubility (in $g L^{- 1}$ ) at $750 torr$ partial pressure is:

$0.0075$

$0.005$

$0.02$

$0.015$

$p = K_{H} X$
where $p \to$ Partial pressure of gas
$X_{2} \to$ Mole fraction of gas in solution
$K_{H} =$ Henry's law constant
So, $p \propto$ solubility
$\frac{p _{1}}{p _{2}} = \frac{s _{1}}{s _{2}} \Rightarrow \frac{500}{0.01} = \frac{750}{x}$
$∴ x = 0.015 g / L$
