dGo = -RTln*K
Solve for Keq.
Then set up Keq expression (remember solids don't enter the expression). You have Keq from above and pO2 is given in the problem, solve for pSO2. Post your work if you get stuck.
Calcium Oxide is used to remove pollutant SO2 from smokestack gases. The ΔG° of the overall reaction
CaO (s) + SO2 (g) + ½ O2 (g) ⇔ CaSO4 (s)
is -418.6 kJ. What is PSO2 in equilibrium with air (PO2 = 0.21 atm) and solid CaO?

I'm still confused what numbers go where?
dGo is -418600
R is 8.314
T is not given but since they say dGo, I assume it is 298 K.
