Suppose a 500. mL flask is filled with 0.20 mol of CHCl$_3$, 0.70 mol of HCl and 0.10 mol of CCl$_4$. The following reaction becomes possible: Cl$_2$(g) + CHCl$_3$(g) $ ightleftharpoons$ HCl(g) + CCl$_4$(g) The equilibrium constant $K$ for this reaction is 0.547 at the temperature of the flask. Calculate the equilibrium molarity of Cl$_2$. Round your answer to two decimal places.
