Stoichiometry
Definition:
(n.) The art or process of calculating the atomic proportions, combining weights, and other numerical relations of chemical elements and their compounds.
Example Sentences:
(1) This formalism allows resolution of the intrinsic protein folding-unfolding parameters (enthalpy, entropy, and heat capacity changes) as well as the ligand interaction parameters (binding stoichiometry, enthalpy, entropy, and heat capacity changes).
