How many kilograms of aluminum metal can be produced by the electrolysis of Al₂O₃ using a current of 100 amperes for 24 hours?

Question

Quizplus · Accepted Answer

The correct answer is A because the amount of aluminum produced by electrolysis is directly proportional to the current and time. The current is 100 amperes and the time is 24 hours, so the total charge passed through the cell is 100 A * 24 h = 2400 Ah. The molar mass of aluminum is 26.98 g/mol, and the number of moles of aluminum produced is 2400 Ah / (3 F/mol) = 800 mol. The mass of aluminum produced is 800 mol * 26.98 g/mol = 21.6 kg.
