Although we tend to make less use of mercury these days because of the environmental problems created by its improper disposal, mercury is still an important metal because of its unusual property of existing as a liquid at room temperature. One process by which mercury is produced industrially is through the heating of its common ore cinnabar (mercuric sulfide, HgS) with lime (calcium oxide, CaO).

4 HgS(s) + 4 CaO(s) → 4 Hg(l) + 3 CaS(s) + CaSO4(s)
What mass of mercury would be produced by complete reaction of 11.4 kg of HgS?
Answer in kg

This should be easy for you to do. Just follow the NH3/CuO/N2 problem done previously.
