“…In particular, one has to recognize the 'Avogadro number' which is equal to the gramto-dalton mass ratio [87] and then stipulate that one mole is the amount of substance which contains the 'Avogadro number' of entities. The proposal by Leonard to recognize explicitly the 'Avogadro number' as the ratio of the gram and the dalton is appealing.…”

Abstract:In the proposed new SI, the kilogram will be redefined in terms of the Planck constant and the mole will be redefined in terms of the Avogadro constant. These redefinitions will have some consequences for measurements in chemistry. The goal of the Mole Project (IUPAC Project Number 2013-048-1-100) was to compile published work related to the definition of the quantity 'amount of substance', its unit the 'mole', and the consequence of these definitions on the unit of the quantity mass, the kilogram. The published work has been reviewed critically with the aim of assembling all possible aspects in order to enable IUPAC to judge the adequateness of the existing definitions or new proposals. Compilation and critical review relies on the broadest spectrum of interested IUPAC members.

“…Leonard argues [86] that one does not need to involve the Avogadro constant in any SI definition and one could simply define the mole in terms of two units of mass: the kilogram and the atomic unit of mass (dalton, see Note 4 in Table 3). In particular, one has to recognize the 'Avogadro number' which is equal to the gramto-dalton mass ratio [87] and then stipulate that one mole is the amount of substance which contains the 'Avogadro number' of entities. The proposal by Leonard to recognize explicitly the 'Avogadro number' as the ratio of the gram and the dalton is appealing.…”

“…Súčasne v ňom okrem nedoriešených odborných metrologických problémov reflektujeme aj aktuálne zavádzanie nových pojmov v prírodovednom vzdelávaní pomocou induktívnej metodológie (Schubertová, 2014). 2007;Rocha-Filho, 2011), ktorá sa nápadne podobá Peterovmu návrhu "mnohosť (Petera, 1988), "avo a "ent (Leonard, 2011a(Leonard, , 2011b(Leonard, , 2011c alebo "uno (Mills, 1995). Tie však podľa Miltona (2011) nemajú potenciál zasiahnuť do plánovaných zmien v SI sústave.…”

Predkladaný príspevok prepája aktuálnu diskusiu o redefinícii základných jednotiek SI sústavy s vyučovaním chémie. Plánovaná definícia mólu má byť založená na presnom stanovení Avogadrovej konštanty. Problémy, ktoré sú spojené s takýmto definovaním mólu, vychádzajú však aj zo samotnej histórie veličiny látkové množstvo. Jedným zo základných problémov tohto charakteru je, že látkové množstvo je spomedzi základných veličín jedinou diskontinuálnou veličinou, ktorej jednotka mól nebola zavedená na základe vlastností prírody, ale na základe ľudskej dohody. Je teda otázne či je mól zaradený medzi základné jednotky SI sústavy logicky správne. Aj z tohto dôvodu je veličina látkové množstvo zaujímavá taktiež z didaktického hľadiska, ktoré je v príspevku diskutované.
