A chemist is studying the following equilibrium:

2Pb(NO3)2 (s) ! 2PbO (s) + 4NO2 (g) + O2 (g) He starts out with 10 g of Pb(NO3)2 and, at equilibrium, has 2.02 g of PbO. The concentrations of NO2 and O2 at equilibrium are 0.25 M and 0.019 M, respectively. What is the value of the equilibrium constant?
