When a calcium carbonate tablet is ingested, it dissolves by the reaction of stomach acid, which contains hydrochloric acid. The unbalanced equation for this reaction is CaCO3(s) + HCl(aq) -----> CaCl2(aq) + H2O(l) + CO2(g). Normal stomach acid contains 3.50% hydrochloric acid. If a particular individual required 9 calcium carbonate tablets to completely neutralize their stomach acid, how many grams of stomach acid reacted? Each calcium carbonate tablet contains 500. mg of the active ingredient.
