Calculate the solubility of a gas in a solvent at $25^{\circ} C$ and $0.8 \ atm$ if Henry's law constant for the solvent is $6.8 \times 10^{-4} \ mol \ dm^{-3} \ atm^{-1}$.

Which among the following salts exhibits an inverse relation between its solubility and temperature?

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 $= 0.4 \ kbar$)

Why are aquatic species more comfortable in cold water in comparison to warm water?

Henry's law constants for $O_2$ and $N_2$ are $K_{O_2} = 3.3 \times 10^7 \ atm$ and $K_{N_2} = 6.51 \times 10^7 \ atm$. Calculate the ratio of $\frac{X_{O_2}}{X_{N_2}}$,i.e.,the ratio of mole fractions of $O_2$ and $N_2$ dissolved in water at $25 \ ^\circ C$ from air. (Assume air contains $20 \%$ $O_2$ and $80 \%$ $N_2$ by volume).

Which of the following is a solution in which the physical states of solute and solvent are liquid and solid respectively?
