Question

an alloy contains 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:

Weight of copper = 52g

Step-by-step explanation:

Copper and zinc are in ratio 2:11

Let us consider the weight of copper as 'x'

=> 2:11 or $\frac{2}{11} = \frac{x}{28.6}$ or x : 28.6

=> 11x = 572

=> x = 52g

Therefore the weight of copper is 52g
