What is stoichiometry?
Quick Answer
Stoichiometry is the part of chemistry that deals with the quantitative relationships in chemical reactions. It tells you how much reactant is needed and how much product will form.
The Full Story
Stoichiometry uses balanced chemical equations to calculate amounts of substances in reactions. It depends on the mole concept and the conservation of mass, first clearly articulated in modern chemistry by Antoine Lavoisier in the late 18th century. By applying coefficients in equations, chemists can predict yields, limiting reactants, and byproducts. Stoichiometry is essential in laboratories, industry, and environmental analysis. It is the mathematical language of chemical reactions.
