What Is Avogadro's Number and Why Is It Important?

TL;DR

Avogadro's number (6.02 x 10^23) defines a mole, representing a large quantity of particles, like atoms or molecules. It is essential for converting between moles and the number of individual particles in chemical calculations, allowing chemists to quantify amounts in a standard way.
