Chemistry Question on Equilibrium

The following concentrations were obtained for the formation of NH3(g)NH_3(g) from N2(g)N_2(g) and H2(g)H_2(g) at equilibrium and at 500K: [N2]1×10−2M,[H2]−2×10−2M[N_2] 1×10^{-2} M, [H_2] -2×10^{-2} M and [NH3]=2×10−2M[NH_3]=2×10^{-2} M. The equilibrium constant, K., for the reaction
N2(g)+3H2(g)2NH;(g)N_2(g)+3H_2(g)2NH; (g) at 500K is
