calculating an equilibrium

Nitrogen and water react to form nitrogen monoxide and hydrogen, like this: N2(g)+2H2O(g)2NO(g)+2H2(g) Also, a chemist finds that at a certain temperature the equilibrium mixture of nitrogen, water, nitrogen monoxide, and hydrogen has the following composition: Calculate the value of the equilibrium constant Kc for this reaction. Round your answer to 2 significant digits
