- TUMS is a popular remedy for acid indigestion. A typical TUMS tablet contains calcium carbonate plus some inert substances. When ingested, it reacts with the gastric juice (hydrochloric acid) in the stomach to give off carbon dioxide gas. When a 1.371 g tablet reacted with 40.00 mL of hydrochloric acid (density 1.140 ), carbon dioxide gas was given off, and the resulting solution weighed 46.699 g. Calculate the number of liters of carbon dioxide gas ml released if its density is 1.81 Be sure your answer has the correct number of significant digits.
