Question

12. An alloy is to contain copper and zinc in the ratio 9:4. Find the quantity of zinc to be melted with 2/25
kg of copper, to get the desired alloy.​

Answer 1

Answer:

This question is from the chapter 'Stoichiometry'.

Step-by-step explanation:

Ratio of amount of copper to amount of zinc= 9:4

Given amount of copper = 2/25 Kg

Let the amount of zinc to be meted be 'X' Kg,

9/4 = 0.08/X

X= 0.08*4/9

X= 8/225 Kg of zinc
