Avogadro’s Number History. The concept is named after Italian scientist Amedeo Avogadro ((1776-1856), who proposed in 1811 that equal volumes of gases at the same temperature and pressure ...

That's not a terrible value for Avogadro's number. Really, it's not. If you take the accepted value of 6.022 x 10 23, then my estimate is just off by less than a factor of 2.

Contrary to the beliefs of generations of chemistry students, Avogadro’s number—the number of particles in a unit known as a mole—was not discovered by Amadeo Avogadro (1776-1856).

Avogadro's number is approximately 6.022x10^23 -- an almost unfathomably large quantity, greater than the number of grains of sand on earth or even the number of stars in the universe.

And yet the Italian chemist Amedeo Avogadro never calculated it. His name became attached to … PITY poor Johann Loschmidt, an Austrian scientist who calculated in 1865 that the number of ...

Avogadro's number is approximately 6.022x10^23 -- an almost unfathomably large quantity, greater than the number of grains of sand on earth or even the number of stars in the universe.

He suggests that if this number—the number of layers and the number of atoms along each hexagonal edge—was equal to 51,150,060, then the total would be 602,214,158,510,196,804,982,800 atoms.

I MUST plead guilty to the charge of not having made a very deep search of the older literature in connexion with the evaluation of ‘Avogadro's Number’. This name has only come into general ...

IN his Rutherford Memorial Lecture1 Sir Charles Darwin writes: “The first estimate of Avogadro's number is due to Maxwell himself”, and expresses his astonishment that Maxwell “should have ...
