Chemistry - Liquid Solution Question with Solution | TestHub

Hydrogen sulphide gas is used in qualitative analysis of inorganic cations. If its solubility in water at S.T.P is 0.195 mole $/\mathrm{kg}$ then its Henry's law constant (in atm, molal ${}^{-1}$ ) for ${\mathrm{H}}_2{\mathrm{S}}_{(\mathrm{g})}$ is
