when CO2 (.15mol) and H2 (.302g) in a 500L vessel at 576'C are allowed to come to equilibrium the mixture contains .000183 mol/L of H20. what is the equilibrium concentration of CO?

CO2 + H2 --> <-- CO +H2O

The equilibrium concentration of H2O = the equilibrium concentration of CO, does it not? Starting from scratch, with zero mol CO and zero mol H2O, 1 mol CO is formed for each 1 mol H2O formed. Check my thinking.
