Problem
Two separate electrolytic cells are connected in parallel across a power supply that delivers a total current of 3.00 A. One cell contains CuSO₄(aq) and has a resistance of 1.20 Ω; the other contains AgNO₃(aq) and has a resistance of 0.80 Ω. If the electrolysis proceeds for 10.0 min, what mass of Ag is deposited?
(Atomic mass: Ag = 107.87 g mol⁻¹)
(a) 0.81 g
(b) 1.21 g
(c) 2.02 g
(d) 0.60 g
