On April 9, 2014, the CCQM held a "Workshop on the Redefinition of the Mole" at the BIPM, chaired by Willie May. The presentations were:
"The new SI, the why and how," R. Davis (BIPM)
"The mole: its history, definition and realization," M. Milton & R. Wielgosz (BIPM)
"The Avogadro constant and the mole," B. Guettler (PTB)
"Revision of the definition of the mole: The position of the Analytical Chemistry Division of IUPAC with
some thoughts on 'teachability'," B. Hibbert, President of the IUPAC Analytical Chemistry Division (IUPAC ACD)
"Issues and concerns on the redefinition of the mole," W. Brand, President of the IUPAC Atomic Weights Commission (CIAAW)
"Redefinition of the mole - issues and concerns," P. De Bievre
"Atomic weights, isotopes and the mole," A. van der Veen (VSL)
"IUPAC Project: 'A critical review of the proposed definitions of fundamental chemical quantities and
their impact on chemical communities'," J. Stohner (IUPAC).
The presentations of Brand, De Bievre and Hibbert were made available by Paul De Bievre to a small group of interested scientists, from whom comments were solicited. Since it is clear from these presentations that a great deal of confusion about the mole, amount of substance, the Avogadro constant (and Avogadro number) and related topics still exists, I offer my comments in the enclosed document.
