How many electrons flow when a current of 5 A is passed through a solution for 200 s? — Electrochemistry Chemistry Question

💡 Solution & Explanation

Total charge $Q = I \times t = 5 \times 200 = 1000$ C. Number of electrons = $Q / e = 1000 / (1.602 \times 10^{-19}) \approx 6.24 \times 10^{21}$ electrons. Therefore, correct answer is B.
