Re: The Audiophoolery Thread.
The calculation is that 1cc and that weighs 8.98 grams for copper. The number of moles is mass/gram atomic weight = 8.98/63.55 = 0.141 moles. 1 mole contains an Avogadro number of atoms. So 0.141 moles in 1cc contains 0.141 x 6 x 10^23 = 8.5 x 10^22 copper atoms. Since each copper atom provides 1 conduction electron, there are therefore 8.5 x 10^22 conduction electrons per cc in copper.
