A thin insulating membrane separates two tanks initially filled with nitrogen [mean cv = 21.6 J/(mol.K)] and carbon-dioxide [mean cv = 11.6 J/(mol.K)] as shown below. The membrane is ruptured and the gases are allowed to mix to form a homogeneous mixture at equilibrium. During this process there are no heat or work interactions between the tank contents and the surroundings. The final temperature at the equilibrium state in Kelvin is
