Stoichiometry Guide: Mass and Mole Relationship
In quantitative chemical analysis, the fundamental bridge between macroscopic laboratory measurements on a digital scale (mass in grams) and microscopic chemical reaction ratios is the mole.
The basic relationship is given by:n = m / Mwhere n is moles, m is mass in grams, and M is molar mass in grams per mole (g/mol).
