1. Charge on 1 electron (\(e^-\)) is \(1.602 \times 10^{-19}\) coulombs: \[e^- \equiv 1.602 \times 10^{-19}\, \text{C}\] 2. Therefore, the number of electrons having a total charge of 1 coulomb is given by: \[= \frac{1}{1.602 \times 10^{-19}} = 6.242 \times 10^{18}\] 3. The number of electrons having a total charge of 1 coulomb is \(6.242 \times 10^{18}\).
