    0.157 moles of Hg will be produced from 34.0 g of HgO.

    Explanation:

    2HgO → 2Hg + O2

    Molar mass of HgO = 216.59 g / mol

    34.0 g / (216.59 g / mol) = 0.156979 mol HgO

    1: HgO: Hg = 1 coefficient ratio (mol defense) because,

    0.156979 mol HgO = 0.156979 mol Hg

    = 0.157 mol of Hg.
