    779 g of chlorine would produce 7.3 moles of AlCl₃

    Explanation:

    Given dа ta:

    Mass of chlorine gas = 779 g

    Number of moles of Aluminium chloride formed = ?

    Solution:

    Chemical equation:

    2AlBr₃ + 3Cl₂ → 2AlCl₃ + 3Br₂

    Number of moles of chlorine:

    Number of moles = mass / molar mass

    Number of moles = 779 g / 71 g/mol

    Number of moles = 11 mol

    Now we will compare the moles of chlorine with Aluminium chloride.

    Cl₂ : AlCl₃

    3 : 2

    11 : 2/3*11 = 7.3 mol

    779 g of chlorine would produce 7.3 moles of AlCl₃.
