Answer:
Option 2. 50 %
Explanation:
Reaction: 2HgO (s) → 2Hg (l) + O₂(g)
Ratio is 2:2, 2 moles of mercury oxide produce 2 moles of liquid mercury.
If you produced 1 mol of Hg, then the percent yield reaction is 50%
Percent yield is:
[Produced yield (what you produced) / Theoretical yield (what you excpected to be produced)] . 100 → (1 mol of Hg / 2 mol of Hg) .100 = 50%
