How many moles of feo are produced
if 8 moles of cufes, are consumed?

8 moles of CuFeS₂   will produced 8 mole of FeO.

Explanation:

Given data:

Moles of CuFeS₂ = 8 mol

Moles of FeO produced = ?

Solution:

Chemical equation:

2CuFeS₂ + 5O₂ → 2Cu + 2FeO + 4SO₂

Now we will compare the moles of CuFeS₂ with FeO from balance chemical equation:

                        CuFeS₂         :           FeO

                             2               :             2

                              8              :             8

8 moles of CuFeS₂   will produced 8 mole of FeO.
