20. How many total electrons are delivered at the cathode during electrolysis if a steady current of — Electrochemistry Chemistry Question

💡 Solution & Explanation

Total charge $Q = I \times t = 1 \text{ A} \times 60 \text{ s} = 60$ C. Number of electrons = $\frac{\text{Total Charge}}{\text{Charge of 1 e}^-} = \frac{60}{1.6 \times 10^{-19}} = 3.75 \times 10^{20}$.
