How many grams of copper will be plated out by a current of 2.3 A applied for 35 minutes to a 0.50 M solution of copper (II)sulfate?

Question

Quizplus · Accepted Answer

The correct answer is A because the amount of copper plated out is directly proportional to the current and the time. The current is 2.3 A and the time is 35 minutes, which is 2100 seconds. The amount of copper plated out is therefore 2.3 A * 2100 s * (1 mol Cu / 2 mol e-) * (63.5 g Cu / 1 mol Cu) = 1.6 g Cu.
