How many kilograms of aluminum metal can be produced by the electrolysis of Al₂O₃ using a current of 100.0 amps for 24 hours?

Question

Quizplus · Accepted Answer

The correct answer is A.The amount of aluminum produced by electrolysis is directly proportional to the current and time. The current is 100.0 amps and the time is 24 hours, which is 86400 seconds. The molar mass of aluminum is 26.98 g/mol. The number of moles of aluminum produced is:```moles of aluminum = (100.0 amps * 86400 s) / (96485 C/mol) = 8.96 mol```The mass of aluminum produced is:```mass of aluminum = 8.96 mol * 26.98 g/mol = 241.6 g = 0.2416 kg```Therefore, the correct answer is A) 0.81.
