When heated, solid mercury oxide (HgO) will decompose into mercury and oxygen gas according to following equation:
2HgO(s) → 2Hg(g) + O2(g)
Starting with a container that has only solid HgO in it, the temperature is raised to 700 K and all of the solid decomposes. The total pressure in the container is 0.75 bar. What is the partial pressure of oxygen? Report your answer in bar to two decimal places.
