Avogadro’s number, number of units in one mole of any substance (defined as its molecular weight in grams), equal to 6.02214076 × 10 23. The units may be electrons , atoms , ions , or molecules , depending on the nature of the substance and the character of the reaction (if any).
Avogadro’s number is a defined value that is exactly 6.02214076×1023. When used as a constant proportionality factor (N A), the number is dimensionless (no units). However, usually Avogadro’s number has units of a reciprocal mole or 6.02214076×10 23 mol -1.
The Avogadro number, sometimes denoted N0, [5][6] is the numeric value of the Avogadro constant (i.e., without a unit), namely the dimensionless number 6.022 140 76 × 1023; the value chosen based on the number of atoms in 12 grams of carbon-12 in alignment with the historical definition of a mole. [1][7] The constant is named after the Italian p...
Avogadro's number, or Avogadro's constant, is the number of particles found in one mole of a substance. It is the number of atoms in exactly 12 grams of carbon -12. This experimentally determined value is approximately 6.0221 x 10 23 particles per mole.
The number \(6.02 \times 10^{23}\) is called Avogadro's number, the number of representative particles in a mole. It is an experimentally determined number. A representative particle is the smallest unit in which a substance naturally exists. For the majority of elements, the representative particle is the atom.
Avogadro's number (Equation \ref{3.2.1}) like any pure number, is dimensionless. However, it also defines the mole, so we can also express N A as 6.02 × 10 23 mol –1; in this form, it is properly known as Avogadro's constant.
Avogadro’s law, a statement that under the same conditions of temperature and pressure, equal volumes of different gases contain an equal number of molecules. This empirical relation can be derived from the kinetic theory of gases under the assumption of a perfect (ideal) gas.
The number \(6.02 \times 10^{23}\) is called Avogadro's number, the number of representative particles in a mole. It is an experimentally determined number.

Avogadro's number is a fundamental constant in chemistry that represents the number of particles (atoms, molecules, or ions) in one mole of a substance. It is a crucial concept in understanding the relationship between the mass of a substance and the number of particles it contains.
Avogadro's Number. Avogadro’s number tells us the number of particles in 1 mole (or mol) of a substance. These particles could be electrons or molecules or atoms. The value of Avogadro’s number is approximately 6.022140857×1023 mol−1. Let us learn more about Avogadro’s number in this article.
