${\mathrm{K}}_{\mathrm{H}}=$ Henry Law constant of gas in water, released to solubility as: Solubility of a gas $\propto \frac{1}{{\mathrm{K}}_{\mathrm{H}}\text{ Value }}$ This means higher is the value of ${\mathrm{K}}_{\mathrm{H}}$, lower will be the solubility of gas in water. $\therefore$ Solubility order of given gas in water $=\mathrm{HCHO}>{\mathrm{CH}}_4>{\mathrm{CO}}_2>\mathrm{Ar}$
