In this paper, it is argued that the SI system has not carefully enough taken into account the differences that exist between stoichiometry and physics, and because of this neglect forced the kind-of-quantity amount of substance into a false form. The mole is not a unit such as the metre, the kilogram, and the second. It is a “unit” only in the sense in which purely mathematical scaling factors can be called units. 
Why dimensionless units should not be used in physics.
The quantities of dimension one - known as the dimensionless quantities - are widely used in physics. However, the debate about some dimensionless units is still open. The paper brings new
The Background and Implications of the "New SI" for Analytical Chemists
The International System of Units (SI) is not in itself a complete philosophical system; it has been developed over time to deal with practical needs. It started during the French revolution with
Alternative interpretations of the mole and the ideal gas equation
The fundamental concept of the mole stems from the idea of the gram-atom (or gram-molecule): that an amount of one mole of a given substance has an associated mass, in grams, numerically exactly
Constancy and Circularity in the SI
The International System of Units (SI) tries to find or construct something that does not change with time and place, since such constancy is the best possible ground for definitions of fundamental
The mole is an Avogadro number of entities, the macroscopic unit for chemical amount

Just as the gram is an Avogadro number of daltons, g = (g/Da) Da, the current definition of the mole can be interpreted as an Avogadro number of entities, as it is often thought of by chemists—and it
Looking back at two decades of “Metrology in Chemistry”
In this Editorial, I am announcing the end of my 16 years of formal responsibility for this Journal as I am becoming slightly subject to biological boundary conditions imposed by mother nature.
About continuity and discreteness of quantities: examples from physics and metrology
The VIM3 defines a quantity as a “property of a phenomenon, body, or substance”, leaving the characteristics of the term ‘quantity’, related to the chosen characteristics of the relevant properties.
Quantities, units and computing
TLDR
The computer representation of quantities and SI units is reviewed at four levels; three implementations (languages, calculators and sensor data transfer) supporting units of measure are examined and some suggestions for a hierarchy of metrological-informatics standards are given.
A critical review of the proposed definitions of fundamental chemical quantities and their impact on chemical communities (IUPAC Technical Report)
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
Quantities as Metrical Coordinative Definitions and as Counts: On Some Definitional Structures in the New SI Brochure
TLDR
The aim of the paper is to uncover never before presented definitional structures in the SI Brochure made by means of the two notions absolutely discrete quantities (counts) and metrical coordinative definitions.

TLDR
This paper argues that a clear and unambiguous scientific distinction should be made between measurement and enumeration, and examines confusion in metrological definitions and nomenclature concerning this distinction.
