Answer:

0.5 moles of HgO will produced 0.25 moles of oxygen

Explanation:

Given data:

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.
