How many electrons are equivalent to one Coulomb?

The correct answer is based on the fundamental relationship between charge and the number of electrons. One Coulomb (C) is defined as the amount of electric charge carried by a steady current of one ampere flowing for one second. The charge of a single electron is approximately 1.602 x 10^-19 coulombs.

To calculate the number of electrons that correspond to one Coulomb, you can divide 1 coulomb by the charge of one electron:

1 C / (1.602 x 10^-19 C/electron) = approximately 6.25 x 10^18 electrons.

Therefore, the answer of 6.25 x 10^18 is correct because it accurately reflects the number of electrons that amount to one Coulomb of charge, confirming the understanding of electric charge at the atomic level.
