Abstract
The SI (2019) claims that the Avogadro constant NA may be used to redefine the mole. In particular, the expression NA = 6.022 140 76 × 1023 × mol-1 is a defining relation whose inversion provides the algebraic definition of the mole. This paper shows that the SI (2019) approach based on the defining relations that is used to redefine the other six base units does not apply to the mole.
