Question

Aluminum metal (Al Al+3) is produced with the same amount of electricity used in producing 550-gram of copper metal (Cul Cu++). (a) Determine the mass of the aluminum produced [Copper = 63.55 g/mol; Aluminum = 26.98 g/mol]

Answer 1

Answer:233.56

Explanation:The molar mass of aluminum (Al) is 26.98 g/mol. We need to find the mass of aluminum produced using the same amount of electricity used to produce 550 grams of copper (Cu).

First, let's find the amount of electric charge used to produce 550 grams of copper using its molar mass:

Moles of copper = mass / molar mass

Moles of copper = 550 g / 63.55 g/mol ≈ 8.665 mol

Since the same amount of electric charge is used for both copper and aluminum, the number of moles of aluminum produced will be the same as the number of moles of copper:

Moles of aluminum = 8.665 mol

Now, let's calculate the mass of aluminum produced using its molar mass:

Mass of aluminum = moles of aluminum × molar mass

Mass of aluminum = 8.665 mol × 26.98 g/mol ≈ 233.56 g

Therefore, the mass of aluminum produced with the same amount of electricity used to produce 550 grams of copper is approximately 233.56 grams.
