4.6 moles SO₃
Explanation:Assuming the equation for the reaction is;4FeS₂ +15O₂ →2Fe₂O₃ + 8SO₃
We are given 2.3 moles of FeS₂We are required to determine the number of moles of SO₃ that are produced.
From the equation 4 moles of FeS₂ reacts with 1 moles of Oxygen to produce 2 moles of Fe₂O₃ and 8 moles of SO₃.Therefore, the mole ratio of FeS₂ to SO₃ is 1 : 2 (4 : 8).Thus, moles of SO₃ = moles of FeS₂ × 2Hence;
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.
