Asked by Sarah

At 23 oC the solubility of a gas sample is 0.05 g/L in water at 1.0 atm. What is the solubility when the pressure increases to 2.0 atm?

I don't know what formula to use for this question.

Henry's Law applies, doesn't it?

you increase pressure by two times, solubility increases twice.
