Question

How many mole of zn(fes2) can be made from 2 mole zinc 3 mole iron and 5 mole sulphur?

Answer 1

In Zn(FeS2)

The mole ratio of Zn : Fe : S = 1 :1 : 2

Which means it contains 1 mole Zn, 1 mole Fe and 2 moles S


2 moles zinc  will require 2  mole iron and 4 mole sulphur to produce 2 moles of Zn(FeS2) 

So, 2 moles of Zn(FeS2) will be formed

Fe will be in excess by 1 mole

S will also be in excess by 1 mole

Answer 2

Answer:

Explanation:

In Zn(FeS2)

The mole ratio of Zn : Fe : S = 1 :1 : 2

Which means it contains 1 mole Zn, 1 mole Fe and 2 moles S

2 moles zinc will require 2 mole iron and 4 mole sulphur to produce 2 moles of Zn(FeS2)

So, 2 moles of Zn(FeS2) will be formed

Fe will be in excess by 1 mole

S will also be in excess by 1 mole
