stoichiometry

 [stoi″ke-om´ĕ-tre]
the determination of the relative proportions of the compounds involved in a chemical reaction. adj., adj stoichiomet´ric.

stoi·chi·om·e·try

(stoy'kē-om'ĕ-trē),
Determination of the relative quantities of the substances concerned in any chemical reaction, for example, with the laws of definite proportions in chemistry, as in the molar proportions in a reaction.
[G. stoicheion, element, + metron, measure]
