1 Coulomb of charge equals [tex]6.25 \times 10^{18}[/tex] electrons. How is this relationship determined?

I don't understand the question. It seems the same as asking "How is 1 mile 5,280 feet ?"
The amount of charge on every electron and every proton is the same. For human people, it's a very small amount of charge, so we work with a larger unit, called the Coulomb. That's the amount of charge on 6.25 x 10¹⁸ electrons .
In a wire, when that many electrons, carrying that amount of charge, pass by some point every second, we call the current in the wire 1 Ampere .

One coulomb of charge corresponds to approximately 6.25 × 1 0 18 electrons due to the charge of a single electron being about − 1.602 × 1 0 − 19 coulombs. By dividing one coulomb by the charge of an electron, we determine the number of electrons needed to equal one coulomb. This is essential in understanding concepts related to electric charge and current.
