Problem
Two identical AgNO₃(aq) electrolytic cells are first connected in parallel to a constant-current source delivering 2.00 A for 5.00 min. Without changing the electrodes or electrolytes, the cells are then reconnected in series to the same source, which still supplies 2.00 A, for an additional 5.00 min. What is the total mass of Ag deposited on one cathode after the full 10.0 min process?
(Atomic mass: Ag = 107.87 g mol⁻¹)
(a) 1.35g
(b) 0.67g
(c) 1.01g
(d) 2.02g
