The typical partial pressure of the carbon dioxide in the atmosphere is 0.0004 atm. In the small gas volume inside a bottle of a carbonated beverage the pressure of the carbon dioxide is 2 atm (this varies widely). What is the ratio of the concentration of carbon dioxide dissolved in the soda before opening (with 2 atm pressure) to post-opening when the carbon dioxide concentration has come to equilibrium with the carbon dioxide in the environment (gone flat)?
