The alloy consists of tin, copper and antimony, taken in a ratio of 1: 2: 5. How many grams of antimony is in the alloy, if there is 6.8 g of copper in it? What is the weight of the alloy?

1) Let’s find out what mass one part will make if it is known that the mass of antimony is 6.8 grams and it takes 2 parts.

6.8 2 = 3.4 grams.

2) Find out the mass of copper in the alloy, if it is known that the mass of one part of the alloy is 3.4 grams, and copper in the alloy is 5 parts.

3.4 * 5 = 17 grams.

3) Find out the mass of the alloy, if it is known that one part of tin is 3.4 grams, copper is 17 grams, and antimony is 6.8 grams.

3.4 + 6.8 + 17 = 27.2 grams.

Answer: the mass of copper in the alloy is 17 grams, and the entire alloy has a mass of 27.2 grams.
