Answer:

1.68 mole mercury produced.

Explanation:

Given data:

Mass of oxygen produced = 27 g

Moles of mercury produced = ?

Solution:

Chemical equation:

2HgO  → 2Hg + O₂

Moles of oxygen:

Number of moles = mass/molar mass

Number of moles = 27 g/ 32 g/mol

Number of moles = 0.84 mol

Moles of mercury produced:

            O₂         :        Hg      

             1           :         2

            0.84     :         2×0.84 = 1.68 mol
