Web1 de jul. de 2006 · The implication was that, like C. P. Snow's claim for knowledge of the Second Law of Thermodynamics as a mark of good education, familiarity with Avogadro's number provides a similar test. The irony is that Avogadro never calculated the number and the eponym was only made 50 years after his death. The Avogadro constant, commonly denoted NA or L, is the proportionality factor that relates the number of constituent particles (usually molecules, atoms, or ions) in a sample with the amount of substance in that sample. It is an SI defining constant with an exact value of 6.02214076×10 reciprocal moles. It was named after the Italian scientist Amedeo Avogadro by Stanislao Cannizzaro, who explained this number four years after Avogadro's death while at the Karlsruhe Congress i…
