What is Avogadro's constant?

Avogadro's constant, also known as Avogadro's number, is a fundamental principle in chemistry that represents the number of particles, atoms, or molecules contained in one mole of a substance. Specifically, Avogadro's constant is approximately 6.02 x 10^23 particles per mole. This value is essential for converting between the number of moles and the number of individual particles in a given sample, which is a crucial concept in stoichiometry and quantitative analysis in chemistry.

The significance of Avogadro's constant lies in its universal application across all substances, enabling chemists to relate macroscopic quantities of matter to the microscopic world of atoms and molecules. Understanding this constant facilitates calculations involving chemical reactions, concentrations, and yields.
