Approximately how many electrons are in one coulomb of electric charge?

Explanation:
The key idea is that charge comes from counting how many elementary charges (electrons) you stack together. An electron carries a charge of about 1.6 × 10^-19 coulombs. To find how many electrons make up 1 coulomb, divide the total charge by the charge per electron: N = 1 C / (1.6 × 10^-19 C per electron) ≈ 6.25 × 10^18 electrons. So one coulomb contains roughly 6.25 × 10^18 electrons, i.e., about 6.25 billion billion electrons. If the charge is negative, it’s the same number of electrons, just with negative sign.
