How many moles of so3 are produced by 2.3 mil fes2

4.6 moles SO₃

4FeS₂ +15O₂ →2Fe₂O₃ + 8SO₃

We are required to determine the number of moles of SO₃ that are produced.

Hence;

Moles of SO₃ = 2.3 moles × 2

                      = 4.6 moles

Thus, 4.6 moles of SO₃ will be produced when 2.3 moles of FeS₂ are used.

c. 4.54 x 10–12 j happens to be correct
