Commercial club soda is produced by pressurizing water with 10 atmospheres of CO2. Find the value of KH for CO2 on the net or the library, and calculate how much CO2 is in 12 fl ox. glass of club soda. When the CO2 reverts to the gas phase (as it eventualy will in your digestive system), figure out how much volume it occupies at physiological conditions (37 C and 1 atm). Then contemplate burping.
