Iron and water react to form iron(III) oxide and hydrogen, like this: 2 Fe(s)+3 H2O(9) - Fe2O3(s)+3H (9) At a certain temperature, a chemist finds that a 7.0 L reaction vessel containing a mixture of iron, water, iron(III) oxide, and hydrogen at equilibrium has the following composition: compound amount Fe 2.58 8 g HO 2.70 g Fe,03 4.89 g H2 3.51 g Calculate the value of the equilibrium constant K, for this reaction. Round your answer to 2 significant digits. K = 0 s
