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 M/atm?

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.
