the option 4
is the solubility of the gas when it exerts a partial pressure of 92.4kPa.
<h3>What is Henry's law?</h3>
Mathematically, we can get this from Henry's law
From Henry law;
Concentration = Henry constant × partial pressure
Thus Henry constant = 
Henry constant = 

Hence,
is the solubility of the gas when it exerts a partial pressure of 92.4kPa.
