    4.23 mol

    Step-by-step explanation:

    Step 1. Balanced equation

    Fe₂O₃ + 3SO₃ ⟶ Fe₂ (SO₄) ₃

    Step 2. Calculation:

    You want to convert moles of SO₃ to moles of Fe₂ (SO₄) ₃.

    The molar ratio is 1 mol Fe₂ (SO₄) ₃:3 mol SO₃

    Moles of Fe₂ (SO₄) ₃ = 12.7 mol SO₃ * (1 mol Fe₂ (SO₄) ₃/3 mol SO₃)

    Moles of Fe₂ (SO₄) ₃ = 4.23 mol Fe₂ (SO₄) ₃

    The reaction will form 4.23 mol of Fe₂ (SO₄) ₃.
