The alloy consists of 6 parts copper and 5 parts zinc. The weight of the alloy is 550 g. How much zinc is there in this alloy?
1. Find how many parts are in the alloy, add the number of parts of copper and zinc:
6 + 5 = 11.
2. If the mass of the alloy is known, we find the mass of one part of the alloy:
550g / 11 = 50g.
3. Find the mass of zinc in the alloy by multiplying the weight of one part by the number of parts of zinc:
5 * 50 = 250 g.
Answer: the alloy contains 250 g of zinc.
