Problem
A production cell is required to generate 25.0 g of aluminum metal each hour from molten Al₂O₃. The process operates at 85.0 % current efficiency. Calculate the minimum constant current (in amperes) that must be supplied to meet this production target. (Molar mass Al = 26.98 g mol⁻¹; reaction at cathode: Al³⁺ + 3 e⁻ → Al)
