    The second sample will produce 1563 grams of fluorine (F2)

    Explanation:

    The reaction will be MgF2 → Mg + F2

    The stoichiometry ratio of MgF2 and F2 is 1 : 1.

    That means for 1 mole of MgF2 consumed there is 1 mole of F2 produced.

    The first sample produces 2.15 kg of magnesium and 3.36 kg of fluorine

    The second sample produced 1 kg of magnesium and x kg of fluorine

    This we can show in the following equation =

    2.15kg / 3.36 kg = 1kg / x

    2.15/3.36 = 0.63988

    0.63988 = 1 / x

    x = 1/0.63988 = 1.563 kg

    1.563kg = 1563 grams

    The second sample will produce 1563 grams of fluorine (F2)
