For which Kc= 1.30*10^2 (Note: Kc not Kp!) ),406 mol of CH3N2CH3(g) are placed in a cylinder that is equipped with a movable piston. The temperature is 300.0 K and the barometric pressure on the piston is constant at 1.00 atm. The origional volume before CH3N2CH3(g) begins to decompose is 10.0 L. What is the volume of the cylinder at equilibrium?
