Stoichiometry / ˌ s t ɔɪ k i ˈ ɒ m ɪ t r i / is the calculation of reactants and products in chemical reactions in chemistry.. 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 typically form a ratio of positive integers.
