When one mole of two ideal monatomic gases, neon and helium, are separated in a partitioned container where each side of the container is having 22.4 L and the temperature of the system is 273 K, The partition is removed and the gases mix.
1. Determine the entropy change for the mixing of the two gases.
2. Repeat all the calculation assuming 0.5 moles of neon and one mole of helium in the same apparatus.
