    2.067 L ≅ 2.07 L.

    Explanation:

    The balanced equation for the mentioned reaction is:

    CS₂ (g) + 3O₂ (g) → CO₂ (g) + 2SO₂ (g),

    It is clear that 1.0 mole of CS₂ react with 3.0 mole of O₂ to produce 1.0 mole of CO₂ and 2.0 moles of SO₂.

    At STP, 3.6 L of H₂ reacts with (? L) of oxygen gas:

    It is known that at STP: every 1.0 mol of any gas occupies 22.4 L.

    using cross multiplication:

    1.0 mol of O₂ represents → 22.4 L.

    ? mol of O₂ represents → 3.1 L.

    ∴ 3.1 L of O₂ represents = (1.0 mol) (3.1 L) / (22.4 L) = 0.1384 mol.

    To find the no. of moles of SO₂ produced from 3.1 liters (0.1384 mol) of hydrogen:

    Using cross multiplication:

    3.0 mol of O₂ produce → 2.0 mol of SO₂, from stichiometry.

    0.1384 mol of O₂ produce →? mol of SO₂.

    ∴ The no. of moles of SO₂ = (2.0 mol) (0.1384 mol) / (3.0 mol) = 0.09227 mol.

    Again, using cross multiplication:

    1.0 mol of SO₂ represents → 22.4 L, at STP.

    0.09227 mol of SO₂ represents →? L.

    ∴ The no. of liters of SO₂ will be produced = (0.09227 mol) (22.4 L) / (1.0 mol) = 2.067 L ≅ 2.07 L.
