2. Avogadro - Proper noun
Italian physicist noted for his work on gases; proposed what has come to be called Avogadro's law (1776-1856)

By fixing the Avogadro constant, the practical effect of this proposal would be that the uncertainty in the mass of a 12 C atom—and the magnitude of the kilogram—could be no better than the current 50 ppb uncertainty in the Planck constant. Source: Internet
As described in Carbon 12 above, this method would define the magnitude of the kilogram in terms of a certain number of 12 C atoms by fixing the Avogadro constant; the silicon sphere would be the practical realization. Source: Internet
Avogadro's number, and its definition, was deprecated in favor of the Avogadro constant and its definition. Source: Internet
Avogadro submitted this essay to a Jean-Claude Delamétherie 's Journal de Physique, de Chimie et d'Histoire naturelle ("Journal of Physics, Chemistry and Natural History", Piedmont at the time forming part of the First French Empire ). Source: Internet
As of the 2006 CODATA recommended values, the relative uncertainty in determinations of the Avogadro constant by the X-ray crystal density method is main, about two and a half times higher than that of the electron mass method. Source: Internet
