    Mass = 507.6 g

    Explanation:

    Given dа ta:

    Mass of Mg = 48 g

    Mass of iodine react = ?

    Solution:

    Chemical equation:

    Mg + I₂ → MgI₂

    Now we will determine the number of moles of Mg.

    Number of moles = mass / molar mass

    Number of moles = 48 g / 24 g/mol

    Number of moles = 2 mol

    Now we will compare the moles of Mg with iodine.

    Mg : I₂

    1 : 1

    2 : 2

    Mass of iodine:

    Mass = number of moles * molar mass

    Mass = 2 mol * 253.8 g/mol

    Mass = 507.6 g
