a How much mercury would a typical employee breathe in if they work for hours a day? The average adult inhales kgday of air. Assume that the mercury content in the room is exactly at the TLV of mu gm
b For the assumed TLV what is the corresponding mol fraction of mercury in air?
c What is the vapour pressure of mercury at oC Compare the two results by using ClausiusClapeyron equation A B oR and Antoine equation?
d What mol fraction of mercury in air corresponds to equilibrium with liquid mercury? Use the number calculated above with Antoine equation.
