A student ran the following reaction in the laboratory at 638 K:

2HI(g) <-----> H2(g) + I2(g)  

When she introduced 0.313 moles of HI(g) into a 1.00 liter container, she found the equilibrium concentration of I2(g) to be 3.10×10-2 M.  

Calculate the equilibrium constant, Kc, she obtained for this reaction.  

Kc = ________
