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 dа ta:

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.
