The Henry's law constant for CO2 in water at 25ºC is 3.4×10-2 mol/L·atm.
(a) Calculate the concentration of CO2 in a beer can with a partial pressure 3.0 atm over the beer at 25 ºC.
(b) Wascana Lake is located in city of Regina. Given that the partial pressure of CO2 is 3.9 × 10-4 atm, calculate the concentration of CO2 at 25 ºC in Wascana Lake.
