1 C charge contains how many electrons:
6 × 1018 electrons
The correct answer is option 4 I.e. 6 × 1018 electrons.
1 coulomb (C) of electric charge contains approximately 6.242 × 1018 electrons.
This is because the charge of one electron is approximately:
1.602 × 10-19
So,
1C / 1.602 × 10-19 C / electron ≈ 6.242 × 1018 electrons = 6 × 1018 electrons.
