A chemistry student wants to design an electrochemical cell that produces a voltage of at least 1.5 volts. The available electrodes are copper and aluminum. Using Faraday's law, calculate the mass of copper needed to produce the required voltage if aluminum is used as the other electrode. The specific gravity of copper is 8.96 g/cm³, and the standard reduction potential of copper and aluminum are -0.34 V and -1.66 V, respectively.
