Hello, Im doing a few practice problems for an upcoming exam and would appreciate your help!

The dissociation of molecular iodine into iodine atoms is represented as

I2(g)<----->2I(g)

At 1000 K the equilibrium constant Kc for the reaction is 3.8 x 10^-5. Suppose you start with 0.0456 mole of I2 in a 2.30 L flask at 1000K. What are the concentrations of the gases at equilibrium?
