Answer:
480.40 g.
Explanation:
2 SO₂(g) + O₂(g) → 2 SO₃(g),
it is clear that 2.0 moles of SO₂ react with 1.0 mole of oxygen to produce 2.0 moles of SO₃.
∵ 2.0 moles of SO₂ produce → 2.0 moles of SO₃, from the stichiometry.
∴ 6.0 moles of SO₂ produce → 6.0 moles of SO₃.
mass = no. of moles x molar mass of SO₃ = (6.0 moles)(80.066 g/mol) = 480.396 g ≅ 480.40 g.
