Muriatic acid, HCl, is often used to remove rust. A solution of muriatic acid, HCl, reacts with Fe2O3 deposits on industrial equipment. How many liters of 5.50 M HCl would be needed to react completely with 439 g Fe2O3? (molar mass of HCl = 36.46 g/mol) (molar mass of Fe2O3 =159.70 g/mol). Use the equation Fe2O3(s) + 6HCl(aq)2FeCl3(aq) + 3H2O to solve this problem.

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".
