The Avogadro constant (symbols: L, NA) is the number of "elementary entities" (usually atoms or molecules) in one mole, that is (from the definition of the mole), the number of atoms in exactly 12 grams of carbon-12.[2][3] It was originally called Avogad
aThe amount of a substance containing a number of particles equal to the number of atoms in 0.012kg of the carbon isotope is called a mole system. 包含一定数量的微粒的相当数量物质相等与原子的数量在碳同位素的0.012kg称痣系统。[translate]

the Avogadro number was defined as the number of atoms in 12 grams of carbon-12 that is as a dimensionless quantity while a mole was defined as one Avogadro number of atoms molecules or other entities. When the mole entered the International System of Units (SI) in 1971 as the...

great number of atoms, molecules, or others in any substance. The mole was originally defined as the number of atoms in 12 grams of carbon-12, but in 2018 the General Conference on Weights and Measures announced that effective May 20, 2019, the mole would be just 6.02214076 × 1023of ...
To interconvert the number of atoms and mass of the compound we need to know Avogadro's Number. Avogadro's Number:Avogadro's number gives us the number of particles in 1 mole of a substance. These particles could be electrons or molecules or atoms. ...

In chemistry and physics, Avogadro's number usually refers to a number of atoms, molecules, or ions, but it can be applied to any "particle." For example, 6.02 x 1023elephants are the number of elephants in one mole of them! Atoms, molecules, and ions are much less massive than elepha...
