Calculate the solubility of a gas in a solvent at a pressure of $3 \text{ atm}$ and $25 \text{ }^\circ\text{C}$. (Given: Henry's law constant $K_H = 3.0 \times 10^{-2} \text{ mol dm}^{-3} \text{ atm}^{-1}$) (in $\text{ M}$)

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

Which of the following is an example of a solution in which the solute is a gas and the solvent is a solid?

Maximum amount of a solid solute that can be dissolved in a specified amount of a given liquid solvent does not depend upon $ . . . . . . $ .
$(i)$ Temperature $(ii)$ Nature of solute $(iii)$ Pressure $(iv)$ Nature of Solvent

Dry air contains $79 \% \,N_2$ and $21 \% \,O_2$. At $T \,K$, if Henry's law constants for $N_2$ and $O_2$ in water are $8.57 \times 10^4 \,atm$ and $4.56 \times 10^4 \,atm$ respectively, the ratio of mole fractions of $N_2$ and $O_2$ dissolved in water at $1 \,atm$ is

Identify a pair of gases from the following that does not obey Henry's law.
