Mole is a unit of counting atoms or molecules in bulk matter. Avogadro's number (6.022 × 10²³) is fundamental in chemistry. Formula mass equals sum of atomic masses of atoms in chemical formula
Molar mass is the mass of one mole of a substance. One mole contains 6.022×10²³ particles. Molar mass is measured in grams per mole (g/mol). Atomic molar mass equals atomic mass in atomic units (u)
Atomic mass is the sum of protons and neutrons in an atom. Mole is defined as amount containing 6.022 × 10²³ atoms of carbon-12. Molar mass is mass of 1 mol of substance in grams
Avogadro's number (NA) is approximately 6.022 x 10²³ particles per mole. NA is constant and applies to all substances. Named after Amedeo Avogadro, who proposed concept in 1811
Molar mass is the weight of one mole of a substance. Standard unit is grams per mole (g/mol), SI unit is kilograms per mole (kg/mol). One mole contains 6.022×10²³ particles
Mole is a unit for counting very large numbers of particles. One mole contains exactly 6.02214076*10²³ elementary entities. Term "mole" introduced by Wilhelm Ostwald in 1896 from Latin 'heap'
