should I use 250 cm^3 or 500 cm^3
1. Consider a container of volume 250 cm that is divided into two compartments of equal size. In the left compartment there is argon at 100 kPa and 0 °C; in the right compartment there is neon at the same temperature and pressure. Calculate the entropy and Gibbs energy of mixing when the partition is removed. Assume ideal mixing and that both gases are ideal.
