Definitions for stoichiometryˌstɔɪ kiˈɒm ɪ tri; -kaɪˈɒm-
This page provides all possible meanings and translations of the word stoichiometry
(chemistry) the relation between the quantities of substances that take part in a reaction or form a compound (typically a ratio of whole integers)
The study and calculation of quantitative (measurable) relationships of the reactants and products in chemical reactions (chemical equations).
The quantitative relationship between the reactants and products of a specific reaction or equation.
Origin: From στοιχεῖον
the art or process of calculating the atomic proportions, combining weights, and other numerical relations of chemical elements and their compounds
Origin: [Gr. a first principle, or element + -metry.]
Stoichiometry is a branch of chemistry that deals with the relative quantities of reactants and products in chemical reactions. In a balanced chemical reaction, the relations among quantities of reactants and products typically form a ratio of positive integers. For example, in a reaction that forms ammonia, exactly one molecule of nitrogen reacts with three molecules of hydrogen to produce two molecules of NH3: This particular kind of stoichiometry - describing the quantitative relationships among substances as they participate in chemical reactions - is known as reaction stoichiometry. In the example above, reaction stoichiometry describes the 1:3:2 ratio of molecules of nitrogen, hydrogen, and ammonia. Stoichiometry can be used to determine quantities such as the amount of products that can be produced with given reactants and percent yield. Stoichiometry calculations can predict how elements and components diluted in a standard solution react in experimental conditions. Stoichiometry is founded on the law of conservation of mass: the mass of the reactants equals the mass of the products.
