Given the reaction 2 HgO(s) → 2 Hg(l) + O₂(g). What weight of elemental mercury will be obtained by the decomposition of 0.125 mol of HgO?

Question

Quizplus · Accepted Answer

The molar mass of HgO is approximately 216.59 g/mol, and the molar mass of Hg is approximately 200.59 g/mol. From the balanced equation, 2 moles of HgO produce 2 moles of Hg. Therefore, 0.125 moles of HgO will produce 0.125 moles of Hg. The weight of 0.125 moles of Hg is 0.125 mol × 200.59 g/mol = 25.07 g, which is closest to 25.0 g.
