The Mole Concept is a fundamental idea in chemistry that helps quantify the amount of a substance. One mole represents 6.022 × 10²³ particles (atoms, molecules, or ions) of a substance, a number known as Avogadro’s number. The mole allows chemists to relate the mass of a substance to the number of particles it contains. For example, one mole of water (H₂O) has 6.022 × 10²³ water molecules and weighs about 18 grams.
