9.3 Exercise 18

Avg difficulty 2.5

Joseph Priestley first prepared pure oxygen by heating mercuric oxide, HgO:
2HgO(s)⟶2Hg(l)+O2(g)2 \text{HgO} \left(s\right) \rightarrow 2 \text{Hg} \left(l\right) + \text{O}_{2} \left(g\right)

(a) Outline the steps necessary to answer the following question: What volume of O2 at 23 °C and 0.975 atm is produced by the decomposition of 5.36 g of HgO?

(b) Answer the question.
