3) A soda can containing 355 mL of a carbonated soft drink is held at 3°C under 2.2 atm
CO2 pressure. What is the concentration of CO2 in the soda, assuming that KH = 7.8 x 10-2
KH = 7.8 x 10^-2 M/atm
So mole CO2 = (2.2 ATM) x (2.2 atm ) =. 0.1516 M
Therefore molar concentration of CO2 = 0.1516/ 0.355 =. 0.427
Answer: 0.427 M.
