Stóchiometriaj is the quantitative study of chemical reactions. It is based on the law of conservation of mass, which states that matter cannot be created or destroyed in a chemical reaction. Stoichiometry uses the balanced chemical equation to determine the relative amounts of reactants and products involved in a reaction. This allows chemists to predict the yield of a reaction and to design experiments to optimize reaction conditions.

The basic principles of stoichiometry involve using mole ratios, which are derived from the coefficients in a balanced chemical equation. For example, in the reaction 2H₂ + O₂ → 2H₂O, the mole ratio of hydrogen to oxygen is 2:1, and the mole ratio of hydrogen to water is 2:2 (or 1:1). These ratios can be used to calculate the amount of product that can be formed from a given amount of reactant, or the amount of reactant that is needed to produce a certain amount of product.

Stoichiometry is essential for many areas of chemistry, including synthesis, analysis, and industrial processes. It is used to determine the amount of reagents needed for a specific synthesis, to calculate the concentration of a solution, and to predict the efficiency of a chemical process. Understanding stoichiometry is fundamental to performing accurate calculations in chemistry and to interpreting experimental results.
