A gas $\mathrm{X}$ is dissolved in water at $2$ bar pressure. Its mole fraction in the solution is $0.02.$ Find the mole fraction of water in the solution when the pressure of the gas is doubled at the same temperature.

Henrys law constant for ${\mathrm{CO}}_2$ in water is $1.67\times {10}^8 \mathrm{Pa}.$ Calculate the approximate quantity of ${\mathrm{CO}}_2$ in $500 \mathrm{ml}$ of soda water when packed under $5 \mathrm{atm} {\mathrm{CO}}_2$ at $298 \mathrm{K}.$

The solubility of ${\mathrm{N}}_2$ in water at $\text{300}\text{K}$ and $\text{500}\text{torr}$ partial pressure is $\text{0}{\text{.01 g L}}^{-\text{1}}.$ The solubility (in ${\text{g L}}^{-\text{1}}$ ) at $\text{750}\text{torr}$ partial pressure is:

${\mathrm{H}}_2\mathrm{S}$, a toxic gas with a rotten egg-like smell is used for the qualitative analysis. If the solubility of ${\mathrm{H}}_2\mathrm{S}$ in water at $\mathrm{STP}$ is $0.195 \mathrm{m}$, Calculate Henry's law constant. (Write the answer without units)

The values of the Henry's law constant of $\mathrm{Ar}, {\mathrm{CO}}_2, {\mathrm{CH}}_4$ and ${\mathrm{O}}_2$ in water at $25°\mathrm{C}$ are $40.30, 1.67, 0.41$ and $34.86 \mathrm{kbar}$, respectively. The order of their solubility in water at the same temperature and pressure is

Identify the correct statement from the following:

Calculate the value of partial pressure needed when $21 \mathrm{mg}$ of ${\mathrm{CO}}_{2 }$ dissolves in $100 \mathrm{g}$ of water at $298 \mathrm{K}$.

(Given that Henry’s constant for ${\mathrm{CO}}_2$is $2.937 \mathrm{kPa} {\mathrm{m}}^3 {\mathrm{mol}}^{-1}$)

$18 \mathrm{mL}$ of hydrogen, measured at STP, dissolves in $1\mathrm{L}$ of water at $20°\mathrm{C}$ and $1.00 \mathrm{atm}$ partial pressure of hydrogen. If the water at $20°\mathrm{C}$ is exposed to a gaseous mixture, containing $68.5\% {\mathrm{H}}_2$ by volume and having a total pressure of $1400 \mathrm{torr}$ (excluding the vapour pressure of water) then find the volume of ${\mathrm{H}}_2$, measured at STP, which will dissolve in $1\mathrm{L}$ of water.
