A 1.00 L flask is filled with 0.106 moles of hydrogen iodide gas (HI) which then begins to decompose into gaseous hydrogen (H2) and lodine (12). At equilibrium, the concentration of HI is found to be 0.078 M. Calculate the equilibrium constant (Kc) for this reaction. 2HI(g)= H2(g) + 2(g) Express your answer using three decimal places.
