Question

an alloy contains Copper and Zinc in the ratio 2 ratio 11 find the weight of copper in the alloy if it has 28.6 gram of zinc

Answer 1

Ratio of copper and zinc IN an alloy = 2:11
Mass of zinc = 28.6 grams (given)
Mass of copper = x (assumed mass)
Similarly, Zinc will be 11x which is equal to 28.6gram.
So, x = 28.6/11
x = 2.6
2x = 2.6 * 2 = 5.2grams
So, the mass of copper is 5.2 grams when mass of zinc is 28.6 grams IN an alloy of copper zinc ratio of 2:11.

Hope this helps you dear!!!

Plz mark my answer brainliest if you find it useful!!!

Answer 2

Ratio of copper and zinc IN an alloy = 2:11

Mass of zinc = 28.6 grams (given)

Mass of copper = x (assumed mass)

Similarly, Zinc will be 11x which is equal to 28.6gram.

So, x = 28.6/11

x = 2.6

2x = 2.6 * 2 = 5.2grams

So, the mass of copper is 5.2 grams when mass of zinc is 28.6 grams IN an alloy of copper zinc ratio of 2:11.
