Stoichiometry is the study of quantitative relationships in chemical reactions a balanced chemical reaction equation gives the mole ratios of the reactants and the products as coefficients when some of the chemical formulas are not known, an experiment can be conducted to help determine the mole. Stoichiometry is important because it explains the relationships of reactants and products in chemical reactions what is a stoichiometry lab. Jeremias benjaim richter (1762-1807) was the first to lay down the principles of stoichiometry in 1792 he wrote: die stöchyometrie (stöchyometria) ist die wissenschaft die quantitativen oder massenverhältnisse zu messen, in welchen die chymischen elemente gegen einander stehen [stoichiometry.

Aluminum metal reacts with hydrochloric acid to form hydrogen gas and an aluminum chloride solution in this investigation, you will predict the mass of hydrogen gas produced by a given amount of reactants, then measure the amount, and compare them. Stoichiometry / ˌ s t ɔɪ k i ˈ ɒ m ɪ t r i / is the calculation of reactants and products in chemical reactions stoichiometry is founded on the law of conservation of mass where the total mass of the reactants equals the total mass of the products, leading to the insight that the relations among quantities of reactants and products.
