The mass of an electron is {tex}9.1 \times 10^{-31}{/tex} kg
Therefore number of electrons in 1kg = {tex}1\over 9.1\times 10^{-31 }{/tex}electrons = {tex}1.09 \times 10^{30 }{/tex}
Electron Number of particles in 1 mole = {tex}6.023 \times 10^{23}{/tex} (Avagadro’s constant)
So , Number of moles ={tex} number \ of \ electrons\over Avagadro’s \ constant {/tex}= {tex}{1.09 \times 10^{30}\over 6.023 \times 10^{23}} = {1.8 \times 10^6}{/tex} electrons
