An old antacid commercial claimed that each tablet of their product could neutralize 47 times its mass in stomach acid. The active ingredient in the antacid tablet, NaAl(OH)₂CO3, reacts with the HCI in stomach acid according to the balanced reaction here. NaAl(OH)₂CO₂ + 4HCI → NaCl + AlCl3 + 3 H₂O + CO₂ How many moles of HCI can a 1.48 g antacid tablet neutralize if the tablet contains 0.354 g of the active ingredient? number of moles of HC1 = mol If stomach acid has a concentration of 0.14 M HCl, determine how many times the tablet's own mass of stomach acid can be neutralized by the 1.48 g antacid tablet. Assume that stomach acid has the density of water, 1.00 g/mL. number of times =

Stoichiometry

Stoichiometry is a chemical division that evaluates the quantitative content of the chemical process with the help of the reacting molecules or products taking part in the reaction. The term “stoicheion” in “Stoichiometry”, is an old Greek term for "element" whereas “metron” means "measure".
