I need help with this question.

If the solubility of a gas in water is 6.0 g/L when the pressure of the gas above the water is 2.0 atm, what is the pressure of the gas above the water when the solubility of the gas is 3.0 g/L?

1 answer

Since solubility is proportional to the pressure, wouldn't that be just half the initial P.
