Calculate the quantity of $CO_2$ required to prepare $1 \,L$ of soda water when the soda water is packed under $2 \,atm$ of $CO_2$. [Henry's law constant for $CO_2$ is $1.67 \times 10^8 \,Pa$] (in $\,g$)

Which of the following gases is least soluble in water at the same temperature and pressure?

If $O_2$ gas is bubbled through water at $303 \; K$,the number of millimoles of $O_2$ gas that dissolve in $1 \; L$ of water is (Nearest Integer). (Given: Henry's Law constant for $O_2$ at $303 \; K$ is $46.82 \; kbar$ and partial pressure of $O_2 = 0.920 \; bar$). (Assume solubility of $O_2$ in water is too small,nearly negligible).

The Henry's law constant for the dissolution of a gas in an aqueous medium is $3 \times 10^2 \ atm$. At what partial pressure of the gas will the molality of the gas in the aqueous solution be $\frac{5}{9} \ m$?

What is solubility? Explain the solubility of a solid solute in a liquid solvent.

At $293 \ K$,methane gas was passed into $1 \ L$ of water. The partial pressure of methane is $1 \ bar$. The number of moles of methane dissolved in $1 \ L$ water is ($K_{H}$ of methane $= 0.4 \ kbar$)
