It requires1200 kg of coal to produce the energy needed to make 1.0 kg of aluminum metal. If a single soda can requires approximately 15 g of Al, what mass of coal would be needed to produce a 6-pack of cans?

1.1 * 10² kg

Explanation:

A single soda can requires approximately 15 g of Al. The mass of aluminum required to produce a 6-pack of cans is:

6 can * (15 g Al / 1 can) = 90 g Al = 0.090 kg Al

It requires 1200 kg of coal to produce the energy needed to make 1.0 kg of aluminum metal. The mass of coal needed to produce 0.090 kg of aluminum metal is:

0.090 kg Al * (1200 kg Coal / 1.0 kg Al) = 108 kg Coal ≈ 1.1 * 10² kg Coal
