(a) Solubility of CO2 at 20 C and 1 atm is equivalent to 87.8 mL/ 100 mL water.Suppose the partial pressure of CO2 before opening a can of coke was 2.5 atm, calculate the molarity of CO2 in a coke saturated with CO2 at 20 C.(b) The 250-mL coke was then opened. Given the atmospheric pressure is 1 atm and volume percent of CO2 in air is 0.036%, what is the solubility of CO2 in the coke at 20 C after exposed to air? And what volume of CO2, measured at 20 C and 1 atm, has expelled after the coke has opened for a prolonged time?

(a) Solubility of CO2 at 20 C and 1 atm is equivalent to 87.8 mL/ 100 mL water.
Suppose the partial pressure of CO2 before opening a can of coke was 2.5 atm, calculate the molarity of CO2 in a coke saturated with CO2 at 20 C.
(b) The 250-mL coke was then opened. Given the atmospheric pressure is 1 atm and volume percent of CO2 in air is 0.036%, what is the solubility of CO2 in the coke at 20 C after exposed to air? And what volume of CO2, measured at 20 C and 1 atm, has expelled after the coke has opened for a prolonged time?
