| :---: | :---: | :---: | :---: | :---: |
| $\mathrm{K}_{\mathrm{H}}$ | 50 | 2 | $2 \times 10^{-5}$ | 0.5 |
density of water $=10^{3} \mathrm{~kg} \mathrm{~m}^{-3}$ at $298 \mathrm{~K}$ ). This table implies that

1 $\alpha$ has the highest solubility in water at a given pressure
2 Solubility of $\gamma$ at $308 \mathrm{~K}$ is lower than at $298 \mathrm{~K}$
3 The pressure of a 55.5 molal solution of $\gamma$ is 1 bar
4 The pressure of a 55.5 molal solution of $\delta$ is 250 bar

1 Different gases have different $\mathrm{K}_{\mathrm{H}}$ (Henry's law constant) values at the same temperature
2 Higher the value of $K_{H}$ at a given pressure, higher is the solubility of the gas in the liquids

4 The partial pressure of the gas in vapour phase is proportional to the mole fraction of the gas in the solution
