Suppose the gauge pressure in a bottle of soda water before it is opened is 15 psig and that the gas mixture is composed of 69% CO₂. If the system is in equilibrium, what is the saturated mass concentration (in mg/L) of CO₂ dissolved in the soda? The Henrys Law constant for CO₂ is 34.1 atm.L/mol. (C = 12, O = 16 g/mol)
