A large tank has twocompartments that are separated by a non-permeable membrane(a gas imperviousbarrier). One side has 1 kg of air with a volume of 0.5m3, and the other side has 0.75m3 of air, with a density of 0.8kg/m3. The barrier is then broken and the air in the roomequilibrates. Determine the final density of the air.(2.387thS)
