Stoichiometry - Chemistry | Socratic

Stoichiometry is the chemistry that mathematically relates all substances in a reaction, quantitatively relating the amount of reactants and products in a chemical reaction. It allows the chemist to determine the amount of product that will form from a given amount of reactants, or the amount of one reactant that is needed to react completely with some specific amount of the other reactant.
