"Electricity is most commonly conducted through copper wires. Copper has a density of 8.94 g/cm and an atomic weight of 63.546 g/mol, so there are 140685.5 mol/m . In one mole of any element, there are 6.022×10 atoms (the Avogadro number). Therefore, in 1 m of copper, there are about 8.5×10 atoms (6.022×10 × 140685.5 mol/m ). Copper has one free electron per atom, so n is equal to 8.5×10 electrons per cubic metre. " - Drift velocity of electron calculator
