    Answer:

    18.0 g of mercury (11) oxide decomposes to produce 9.0 grams of mercury

    Explanation:

    Mercury oxide has molar mass of 216.6 g/ mol. It gas a molecular formula of HgO.

    The decomposition of mercury oxide is given by the chemical equation below:

    2HgO —-> 2Hg + O₂

    2 moles of HgO decomposes to produce 1 mole of Hg

    2 moles of HgO has a mass of 433.2 g

    433.2 g of HgO produces 216.6 g of Hg

    18.0 of HgO will produce 18 × 216.6/433.2 g of Hg = 9.0 g of Hg

    Therefore, 18.0 g of mercury (11) oxide decomposes to produce 9.0 grams of mercury
