Constants I Periodic Table

The concentrations of reactants and products for a chemical reaction can be calculated if the equilibrium constant for the reaction and the starting concentrations of reactants and$/$or products are known.

Part A

Carbonyl fluoride, $CO{F}_2,$ is an important intermediate used in the production of fluorine$-$containing compounds. For instance, it is used to make the refrigerant carbon tetrafluoride, $C{F}_4$ via the reaction

$2CO{F}_2(g)C{O}_2(g)+C{F}_4(g),K_c=4\mathrm{.}40$

If only $CO{F}_2$ is present initially at a concentration of $2\mathrm{.}00M,$ what concentration of $CO{F}_2$ remains at equilibrium?

Express your answer with the appropriate units.
