Question

solve it in how many coulomb has 12.50×10^18electrons ?​

Answer 1

Answer:20×10⁻¹¹ Coulomb

Explanation:

1 electron carries a charge of -1.6×10⁻¹⁹C

12.5×10⁸ electrons will carry a charge of -12.5×1.6×10⁻¹¹C

which is equal to 20×10⁻¹¹C or 2×10⁻¹⁰C,

So the answer is 20×10⁻¹¹C or 2×10⁻¹⁰C

Well that’s pretty impressive because, you take the amount of electrons that is roughly 4 times, the amount of meters travelled by light in one second, to only get a charge of -2 in every 10 billion C.

Thats pretty cool!!!
