When dinitrogen pentoxide is heated to 650 K, it decomposes to dinitrogen trioxide and molecular oxygen according to the reaction:

N₂O₅(g) N₂O₃(g) + O₂(g) K_c = 0.0650 at 650 K

If the initial concentration of N₂O₅ in the 2.50 L flask is 0.150 M, then what is the number of moles of N₂O₅ at equilibrium in a 2.50 L flask.
