The partial pressure of CO_2 in the atmosphere is 3.9e10^-4. When drinking soda it is put in a can, assume there is 2.0atm CO_2 in the 2.0mL gas space above the soda. What is the approximate ratio of the molar concentrations of CO_2(aq) in the soda before it is opened to that in the soda after it has been opened and reached equilibrium with the surrounding atmosphere; i.e., has "gone flat?" I know the answer is 5e10^3, but I'm not sure how you get there. Please show clear work for credit.
