mass of electron = 9.1 × 10-³¹ Kg
mass of one mole electrons = 6.023 × 10²³ × 9.1 × 10-³¹ Kg = 5.48093 × 10^-8 Kg
Let number of electron = n
n = 1 Kg/{ 5.48093 × 10^-8} Kg
= 10/5.48093 × 10^7
=1.824 × 10^7

Answer:10^8/9.108*6.023
Step-by-step explanation:wt. Of 1 electron =9.108*10^-31
In 1mloe 6.023*10^23 particles present.
So. In 1 mole 6.023*9.108*10^24*10^-31electron.
1mole electron =6.023*9.108*10^24*10^-31kg
No. of mole in 1kgelectron
=1/9.108*6.023*10^
10^8/9.108*6.023
