A student wants to determine the power output of a galvanic cell containing a zinc electrode and a copper electrode. The zinc electrode has a surface area of 20 cm² and is coated with a layer of zinc which weighs 0.5 grams. The copper electrode has a surface area of 15 cm² and is coated with a layer of copper that weighs 0.4 grams. The cell operates at standard conditions (25°C and 1 atm), and the electrolyte is a solution of 1 M copper sulfate and 1 M zinc sulfate. Calculate the power output of the electrochemical cell.
