    0.5 moles of HgO will produced 0.25 moles of oxygen

    Explanation:

    Given dа ta:

    Number of moles of HgO = 0.5 mol

    Number of moles of oxygen = ?

    Solution:

    Chemical equation;

    2HgO → 2Hg + O₂

    WE will compare the moles of HgO with oxygen from balance chemical equation.

    HgO : O₂

    2 : 1

    0.5 : 1/2*0.5 = 0.25 mol

    So 0.5 moles of HgO will produced 0.25 moles of oxygen.
