50.0g of N2O4 is introduced into an evacuated 2.00L vessel andallowed to come to equilibrium with its decomposition product, N2O4-> 2NO2. for this reaction Kc = .133. Once the system hasreached equilibrium, 5.00g of NO2 is injected into the vessel, andthe system is allowed to equilibrate once again. Calculate the mass of NO2 in the final equilibrium mixture.
