Henry's law constant for the solubility of $$\mathrm{N}_2$$ gas in water at $$298 \mathrm{~K}$$ is $$1.0 \times 10^5 \mathrm{~atm}$$. The mole fraction of $$\mathrm{N}_2$$ in air is 0.8 . The number of moles of $$\mathrm{N}_2$$ from air dissolved in 10 moles of water at $$298 \mathrm{~K}$$ and $$5 \mathrm{~atm}$$ pressure is

$$4.0 \times 10^{-4}$$

$$4.0 \times 10^{-5}$$

$$5.0 \times 10^{-4}$$

$$4.0 \times 10^{-6}$$

Choose the correct statement.

$$K_{\mathrm{H}}$$ value is same for a gas in any solution.

Higher the $$K_{\mathrm{H}}$$ value more the solubility of gas.

$$K_{\mathrm{H}}$$ value increases on increasing the temperature of the solution.

Easily liquefiable gases usually has lesser $$K_{\mathrm{H}}$$ values.
