The alloy contains 3 parts of copper and 4 parts of zinc. How much zinc does an alloy with a total weight of 84 kg contain?
Since the alloy contains 3 parts of copper and 4 parts of zinc (this alloy is brass), it means that each kilogram of this alloy consists of seven parts in an element ratio of 3: 4.
If the alloy has a mass of 84 kg, then 1/7 of it will be: 84/7 = 12 kg.
Since zinc occupies 4 parts in the alloy, its mass is: 12 * 4 = 48 kg.
Answer: An alloy weighing 84 kg contains 48 kg of zinc.
