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.

A chemistry student is given a sample of an unknown salt consisting of a mixture of two compounds. The student is asked to determine the percentage composition of each compound in the salt using mass balance calculations. The total mass of the sample is 10 grams, and after performing careful analysis, the student obtains the following data: One compound has a molar mass of 80 g/mol and comprises 60% of the total mass of the salt. The other compound has a molar mass of 120 g/mol and comprises 40% of the total mass of the salt. What are the percentage compositions of each compound in the salt?
