| An alloy weighing 350 g consists of copper and zinc. The ratio of copper mass to zinc mass is 3: 4. Find the mass of copper in the alloy.
Let’s find how many fractions of both metals are included in the alloy:
3 + 4 = 7.
Let’s find how many grams of alloy are in each share:
350/7 = 50 grams.
There are only 3 parts of copper in this alloy. Let’s find its mass in the alloy:
50 * 3 = 150 grams.
Answer: The mass of copper in a copper-zinc alloy is 150 grams.
