    Theoretical yield of CCl₄ = 72.3 g

    Explanation:

    Given dа ta:

    Mass of Cl₂ = 100.0 g

    Theoretical yield of CCl₄ = ?

    Solution:

    Chemical equation:

    CS₂ + 3Cl₂ → CCl₄ + S₂Cl₂

    Number of moles of Cl₂:

    Number of moles = mass/molar mass

    Number of moles = 100 g / 71 g/mol

    Number of moles = 1.41 mol

    Now we will compare the moles of Cl₂ with CCl₄.

    Cl₂ : CCl₄

    3 : 1

    1.41 : 1/3*1.41 = 0.47 mol

    Theoretical yield of CCl₄:

    Mass = number of moles * molar mass

    Mass = 0.47 mol * 153.82 g/mol

    Mass = 72.3 g
