===About the Avogadro Constant===
: The '''Avogadro Constant''' is used to state the number of [[atom]]s or [[molecule]]s in a [[mole]] of a [[substance]].
: The '''Avogadro Constant''' is normally written in standard form.: as '''6.02x10<sup>23</sup>''' = '''602,000,000,000,000,000,000,000''' correct to 3 [[Significant Figures]].
: 1 [[mole]] of an [[element]] contains '''6.02x10<sup>23</sup>''' [[atom]]s of that [[element]].
: 1 [[mole]] of a [[molecule]] contains '''6.02x10<sup>23</sup>''' [[molecule]]s.

===Meaning===
The [[Avogadro Constant]] is the number of atoms in 12 grams of carbon-12, approximately '''6.02 x 10^02x10<sup>23 </sup>''' atoms per [[mole]].
===About the Avogadro Constant===
*The [[Avogadro Constant|Avogadro constant]] is a fundamental constant in chemistry and physics.
*The [[Avogadro Constant|Avogadro constant]] is used to calculate the number of [[particle]]s in a given amount of substance.
*One [[mole]] of any substance contains [[Avogadro Constant|Avogadro]]'s number of particles.*The value of the [[Avogadro Constant|Avogadro constant]] is '''6.02x10<sup>23</sup>''' mol<sup>-1</sup>.*It is used in determining the [[Molar Mass|molar mass]] of substances.*The [[Avogadro Constant|Avogadro constant]] is essential for converting between [[atom]]ic scale and macroscopic scale measurements.*The [[Avogadro Constant|Avogadro constant]] is named after the Italian scientist [[Amedeo Avogadro]], who first proposed the concept.
