Calculate the number of electrons constituting one coulomb of charge.

(N/A) One electron possesses a charge of $1.6 \times 10^{-19} \, C$,which means $1.6 \times 10^{-19} \, C$ of charge is contained in $1$ electron.
Using the formula $Q = ne$,where $Q = 1 \, C$ and $e = 1.6 \times 10^{-19} \, C$:
$n = \frac{Q}{e} = \frac{1}{1.6 \times 10^{-19}} = 0.625 \times 10^{19} = 6.25 \times 10^{18}$.
Therefore,$6.25 \times 10^{18}$ electrons constitute one coulomb of charge.
