The alloy consists of tin and zinc, the mass of which is 9: 8, the weight of the alloy is 2 kg 550 g. How much zinc is in this alloy
1. To solve this problem, we need to find out how many parts are in the alloy.
9 + 8 = 17 pieces
2. Find out the weight of one part if the weight of the alloy is 2kg. 550 grams.
2kg 550g = 2550g
2550/17 = 150 gr. weight of one piece.
3. Since there are 8 parts of zinc in the alloy and each part weighs 150 grams, we get:
8 * 150 = 1200 gr., Which equals 1kg. 200 grams.
Answer: the alloy contains 1 kg. 200 grams of zinc.
