Concepts of Quantitative Composition
The objective of this book is to interpret the chemist’s shorthand — chemical symbolism and formulation — and to introduce the subject of stoichiometry. Stoichiometry is the branch of chemical mathematics concerned with the relative amounts of substances that interact. Derived from the Greek stoicheion, meaning element, stoichiometry originally treated only of the different weights of elements that combine to form specific compounds. Modern usage, however, has expanded the generic applicability of the term to any and all aspects of chemical reactivity that can be validly interpreted by a balanced chemical equation. Consequently, stoichiometry encompasses within its purview not only weights but also volumes, gaseous and liquid, and even thermochemical and photochemical quanta of reaction.
