$\underline{\mathsf{Answer}}$

Avogadro's Constant

The Avogadro's constant 6.022 × 10²³ is defined as the number of atoms exactly in 12g of carbon - 12.

Avogadro's constant is denoted by Nₐ

Nₐ = 6.022 × 10²³ particles [atoms, molecules, ions]

Formula's that have Avogadro's Constant

→  No: of moles = $\frac{\mathsf{Mass \ In \ Grams}}{\mathsf{Atomic \ Number}}$ × Nₐ

→ $\mathsf{No: \ of \ Particles\ = \ No: \ of \ moles \ * \ Nₐ}$

[Note: In Na, the subscript 'a' is in capital]
