• Resumen

  • The term stoichiometric amount is proposed as a substitute or a synonym for the problematic SI-base quantity amount of substance. The word stoichiometric not only makes the term highly specific in modifying the word amount, but also signals that the expression is a technical term rather than a phrase of common English words. The term can be usefully employed in explaining the mole (i.e., as a unit of stoichiometric amount) regardless of the official name of the quantity of which the mole is a unit. It can be used alongside the phrase chemical amount, which has previously been proposed as an alternative to amount of substance.
