The statement "The mass of a gas dissolved in a given mass of a solvent at any temperature is proportional to the pressure of the gas above the solvent" is

Assertion : Iodine is more soluble in water than in carbon tetrachloride.
Reason : Iodine is a polar compound.

The solubility of a gas in water depends on

Explain the solubility of a solution formed by a gaseous solute and a liquid solvent.

Given below are two statements:
Statement $I$: The Henry's law constant $K_{H}$ is constant with respect to variations in solution's concentration over the range for which the solution is ideally dilute.
Statement $II$: $K_{H}$ does not differ for the same solute in different solvents.
In the light of the above statements, choose the correct answer from the options.

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 $\text{ M}$)
