1. Inside a rigid container, a mixture of three ideal gases with mass fractions of 30% N2, 50% O2 and 20% CO2 has a total mole of 10 kmol.

a. What's the molar mass of the mixture?

b. What are the specific heats (cv and cp) of the mixture?

c. Determine the heat transfer needed to raise the temperature of this mixture from 0°C to 50°C.

2. An insulated rigid tank is divided into two compartments by a partition, as shown in the following figure. One compartment contains 2 kg of oxygen gas at 50°C and 200 kPa, and the other compartment contains 3 kg of nitrogen gas at 30°C and 350 kPa. Now the partition is removed, and the two gases are allowed to mix. Determine (a) the mixture temperature and (b) the mixture pressure after equilibrium has been established.
