What is a Mole? A mole is the SI unit of measurement for amount of substance. Just as a "dozen" refers to 12 items, a "mole" refers to a specific, very large number of particles. 1 Mole = 6.022 × 10 23 particles This value is known as Avogadro's Number ($N_A$) . 2. Molar Mass Molar mass is the mass of one mole of a substance (atoms, molecules, or formula units). It is numerically equal ...
