A Critique on the Definition of the si Unit Mole

Authors: Radhakrishnamurty Padyala

The Draft Chapter 2 for SI Brochure, following redefinition of the base units states, that the XXth CGPM adopted a new definition of the mole. A committee is set to redefine four base units – the ampere, the kilogram, the Kelvin and the mole. We find inconsistencies in the units of molar mass, molecular mass and the relation connecting them through Avogadro constant. There are also problems with the symbols and the terms ‘entity’ used in the definition of mole and the role of isotopes in the specification of an entity X. We give a critical analysis of these issues in this article.
