# What Is Stoichiometry?

Stoichiometry is a branch of chemistry concerned with the relative quantities of reactants and products in chemical reactions. It deals with the application of the laws of explicit proportions plus the conservation of mass and energy.

NOUN
1.
the calculation of the quantities of chemical elements or compounds involved in chemical reactions.
2.
the branch of chemistry dealing with relationships of combining elements, especially quantitatively.

Stoichiometry is the math behind the science of chemistry. Using known physical laws such as the law of conservation of mass, and the law of definite proportions, stoichiometry is used to gather information about the amounts of various elements used in a chemical reaction, and whether they took the form of gases, solids, or liquids.
Stoichiometry deals with calculating the amounts of substances that are involved in reactions, including reactants, catalysts, and substances produced by the reaction. You can find more information here: http://www.chem4kids.com/files/react_stoichio.html
