An equilibrium mixture of SO2, O2, and SO3 at 1000 K contains the gases at the following concentrations: [SO2] = 3.77 10-3 mol/L, [O2] = 4.30 10-3 mol/L, and [SO3] = 4.13 10-3 mol/L. Calculate the equilibrium constant, K, for the following reaction.
2 SO2(g) + O2(g) ---> 2 SO3(g)

Thanks. I put them in the Keq equation and solved and got .279. What am I doing wrong?
