“…Among early published uses of the term, it appears that some users intended it to refer to a number of entities, but others intended it to refer to a mass of material. The distinctions between these conceptually different uses of the term are subtle and have only been explained clearly by Stille [15]. It is a mistake to assert that the amount of substance has solely the character of one, to the exclusion of the other.…”

The mole is the most recent addition to the set of base units that form the International System of Units, although its pre-cursor the 'gram-molecule', had been in use by both physicists and chemists for more than 120 years. A proposal has been published recently to establish a new definition for the mole based on a fixed value for the Avogadro constant. This would introduce consistent relative uncertainties for the molar and the atomic masses while making no change to the system of relative atomic masses ('atomic weights'). Although the proposal would have little impact on the measurement uncertainty of practical work, it has stimulated considerable debate about the mole and the nature of the quantity amount of substance. In this paper, the rationale for the new definition is explained against the background of changes in the way the quantity amount of substance has been used, from its first use during the early development of thermodynamics through to the use of the 'number of gram-molecules' at the end of the nineteenth century.

“…Its incorporation into the vocabulary of English-speaking chemists was the result of a carefully considered proposal by Prof EA Guggenheim who argued that ''it can sometimes be useful in dimensional analysis to regard the number of atoms as having dimensions different from a pure number'' [9]. He proposed that the term amount of substance be used as the name for the quantity for which the mole is the unit and justified the choice as a translation of the noun Stoffmenge [10,11] in use by German chemists.…”
