Work Step by Step
Because the question is dealing with solubility and pressure, we need to use Henry's law, in which solubility (S) of a gas in a liquid is directly proportional to the pressure (P) of the gas above the liquid.
Plug the known values into Henry's law and solve for the unknown solubility with the different pressure. Notice how solubility increases as the pressure increased, making the answer we obtained reasonable.
