stoichiometry

Determination of the proportions (by weight or number of molecules) in which elements or compounds react with one another. The rules for determining stoichiometric relationships are based on the laws of conservation (see conservation law) of mass and energy and the law of combining weights (see equivalent weight) or volumes. The tools used are chemical formulas, chemical equations, atomic weights, and molecular weights or formula weights.
