If N is Avogadro number, M is atomic weight and \(\rho\) , the density, the number of free electrons per unit volume of a monovalent metallic crystal can be expressed as
- \(\frac{\rho \mathrm{N}}{\mathrm{M}}\)
- \(\frac{\mathrm{N}}{\mathrm{ \mu M}}\)
- \(\frac{\mathrm{MN}}{\rho}\)
- \(\frac{\rho M}{N}\)
Answer
(A) N M
