⚖️ What is a Mole?
The mole is the SI unit for amount of substance. One mole contains exactly 6.02214076 × 10²³ elementary entities (Avogadro’s number).
1 mol = 6.022 × 10²³ particles
This number was chosen so that the mass of one mole of a substance, measured in grams, is numerically equal to its atomic/molecular mass.
🔢 Avogadro’s Number
Avogadro’s number (Nₐ) is the number of constituent particles (usually atoms or molecules) in one mole of a given substance.
Nₐ = 6.02214076 × 10²³ mol⁻¹
This enormous number connects the microscopic world of atoms and molecules to the macroscopic world we can measure.
