The partial pressure of CO2 inside a bottle of soft drink is 4.0 atm at 25°C. The solubility of CO2 is 0.12 mol/L. When the bottle is opened, the partial pressure drops to 3.0 ✕ 10-4 atm. What is the solubility of CO2 in the open drink? Express your answer in grams per liter.

Henry's Law says concn is proportional to pressure; therefore,
0.12 x (3E-4/4) = ? M = ? mols/L.
Convert to grams/L.
