Many antacid tablets contain calcium carbonate (CaCO3). Calcium carbonate reacts with HCl in the stomach to produce water, calcium chloride, and carbon dioxide. At 37°C and 1 atm, what volume (in L) of CO2 is produced when a person consumes a Rolaids antacid tablet that contains 550.0 mg of CaCO3 to eliminate excess stomach acid?
Assume acid is in excess of the carbonate. (R = 0.08206 L.atm/K. mol)
1 mg = 0.001 g
