Question
How many electrons will have a total charge of 1 Coulomb ?
✓
Answer
Given : Charge $=1$ Coulomb Number of electrons $=$ ? 1 Faraday $=96500 C$ per mol electrons $\because 96500$ C electric charge is present on 1 mol electrons $\therefore 1 C$ charge is present on $\frac{1}{96500}$ mol electrons $\therefore$ Number of electrons $=\frac{1}{96500} \times 6.022 \times 10^{23}$ $=6.24 \times 10^{18}$ electrons 1 Coulomb charge is present on $6.24 \times 10^{18}$ electrons.
