Problem
Two electrolytic cells are connected in parallel across the same 12.0 V power supply. The branch containing a Ni²⁺(aq) cell has a resistance of 4.0 Ω, and the branch containing a Cu²⁺(aq) cell has a resistance of 6.0 Ω. The total current drawn from the supply is 3.00 A and the cells run for 25.0 min. Determine the mass of nickel deposited in the first cell and the mass of copper deposited in the second cell. (Molar masses: Ni = 58.69 g mol⁻¹, Cu = 63.55 g mol⁻¹)
