As we learned

Henry's Law -

It decides the solubility of gases in liquids.

$P_{gas}= K_{H}X_{gas}$

$X_{gas}$ = mole fraction of gas in liquid.

$P_{gas}$ = Partial pressure of gas over liquid surface.

-

$Solution\propto Pressure$

$\frac{S_{2}}{S_{1}}=\frac{P_{2}}{P_{1}}$

$S_{2}=5.3\times 10^{-4}\times \frac{760}{593}=6.8\times 10^{-4}M$

Option 1)

4.1 × 10-4 M

Option 2)

6.8 × 10-4 M

Option 3)

1500 M

Option 4)

2400 M
