- Avogadro, Amedeo 1776-1856. Italian chemist and physicist who advanced the hypothesis that has come to be called Avogadro's law. From this hypothesis other physicists were able to calculate Avogadro's number.

Sorry, no etymologies found.
One of the many anecdotes Matt Haimovitz likes telling about his current cross-country tour takes place in a Fort Collins, Colo., dive called Avogadro's Number.
This number, known as Avogadro's constant, is of great importance.
Joseph Louis Gay-Lussac (1808) showed that a sample of gas, at a fixed pressure, increases in volume linearly with the temperature, i.e. Gay-Lussac's law of combining volumes to state what is now commonly called Avogadro's law: equal volumes of any two gases at the same temperature and pressure contain the same number of molecules.
The number of atoms per mole is known as Avogadro's number, NA.
The Amount of Substance Whatever this number is (it ‟ s actually called Avogadro ‟ s number and is approximately 602 214 179 000 000 000 000 000 or in scientific notation, 6.02214179 x 1023) the important thing is that this idea of number of atoms gives us a way of measuring the amount of carbon, which chemists find very useful.
(L22) - Chemical Accounting • One of the most important numbers in chemistry: Avogadro's number Avogadro's number: The number of atoms in a 12-g sample of carbon-12 is called Avogadro's number Avogadro's number has been experimentally determined to be 6. 0221367×1023 But, 6. 02×1023 is sufficiently enough for our purpose in general chemistry
It was at Stanford that a fellow student explained the Pancake Theory of Knowledge, a kind of Avogadro's Number for the liberal arts, that I describe in
In 1811 [[Amedeo Avogadro]] re-interpreted Gay-Lussac's law of combining volumes to state '' Avogadro's law '': equal volumes of any two gases at the same temperature and pressure contain the same number of molecules.
Mr. Stein also addresses fundamental limits like the speed of light and absolute zero in temperature, practical measures such as Avogadro's number describing the number of molecules in a fixed quantity of a gas, and cosmological parameters like the Schwarzschild radius, fixing the distance at which nothing can escape from a black hole.
Atom-counting approaches (I liked the Avogadro project, which would use a silicon sphere); Ion accumulation; and the rather sexy sounding watt balance method: the electronic kilogram!
