AI Generated Solution

To solve the problem step by step, we will first calculate the weight of zinc that can be plated on the cathode and then determine the thickness of the coating layer. ### Step 1: Calculate the total charge passed through the solution The formula for charge (Q) is given by: \[ Q = I \times t \] where: - \( I \) = current in amperes (A) - \( t \) = time in seconds (s) ...
