Question

Calculate the charge carried by 20 × 10^18 electrons.​

Answer 1

Explanation:

Given,

Number of electrons = 20 X 10^18

Charge on 1 electron = 1.6 X 10^-19

Charge = Number of electrons X Charge on 1 electron

After substituting value,

= 20 X 10^18 X 1.6 X 10^-19

= 20 X 1.6 X 10^18 X 10^-19

= 2 X 10 X 1.6 X 10^18 X 10^-19

= 3.2 X 10^19 X 10^-19

= 3.2 Coulomb
