The container shown in the figure has two chambers, separated by a partition, of volumes V1=2.0 L and V2=3.0 L. The chambers contain μ1=4.0 mole and μ2=5.0 mole of a gas at pressures p1=1.00 atm and p2=2.00 atm. Calculate the pressure after the partition is removed and the mixture attains equilibrium.
