The total number of conduction electrons is:
The number density of conduction electrons in a sample is the number of conduction electrons per unit volume:
We can relate the number of atoms in a sample to various properties of the sample and the material making up the sample with the following:
where the molar mass is the mas of one mole of the material in the sample and is Avogadro's number.

The total number of conduction electrons is:
(number of conduction electrons in sample)=(number of atoms in sample)⋅(number of valence electrons per atom)(1)(1)(number of conduction electrons in sample)=(number of atoms in sample)⋅(number of valence electrons per atom)
The number density nn of conduction electrons in a sample is the number of conduction electrons per unit volume:
n=number of conduction electrons in samplesample volumeV(2)(2)n=number of conduction electrons in samplesample volumeV
We can relate the number of atoms in a sample to various properties of the sample and the material making up the sample with the following:
(number of atoms in sample)=sample massMsamatomic mass=sample massMsam(molar mass)M)/NA=(material's density)⋅(sample volumeV)(molar massM)/NA(3)(4)(5)(3)(number of atoms in sample)=sample massMsamatomic mass(4)=sample massMsam(molar mass)M)/NA(5)=(material's density)⋅(sample volumeV)(molar massM)/NA
where the molar mass MM is the mas of one mole of the material in the sample and NANAis Avogadro's number.
