\green{\underline\textbf{Mole}}

⏭️⏭️The mole is the unit of measurement for amount of substance in the International System of Units. A mole of a substance or a mole of particles is defined as exactly 6.02214076×10²³ particles, which may be atoms, molecules, ions, or electrons. In short, for particles 1 mol = 6.02214076×10²³. ⏮️⏮️

\green{\underline\textbf{Avogadro number}}

⏭️⏭️The Avogadro constant, usually denoted by NA or L is the factor that, multiplied by the amount of substance in a sample, measured in moles, gives the number of constituent particles in that sample. Its unit is the reciprocal of mole, and it is defined as NA = 6.02214076×10²³ mol⁻¹.⏮️⏮️
