Question

an alloy contain copper and zinc in the ratio of 2:11. Find the weight of copper in the alloy,if it has 28.6 grams of zinc.​

Answer 1

Answer:

Let the weight of copper be X

Ratio of alloy = 2:11 = 2/11

Weight of zinc = 28.6 grams

A/q

2/11 = X/28.6

=> 11×X = 28.6×2

=> 11X = 57.2

=> X = 57.2/11

=> X = 5.2

Hence,

Weight of copper = 5.2 grams
