Question
Henry’s constant (in kbar) for four gases $\alpha $, $\beta $, $\gamma $ and $\delta $ in water at 298 K is given below :

$\alpha $ $\beta $ $\gamma $ $\delta $
KH 50 2 2 $ \times $ 10-5 0.5

(density of water = 103 kg m-3 at 298 K)
This table implies that :
solubility of $\gamma $ at 308 K is lower than at 298 K
The pressure of a 55.5 molal solution of $\delta $ is 250 bar
$\alpha $ has the highest solubility in water at a given pressure
The pressure of a 55.5 molal solution of $\gamma $ is 1 bar
