A gas mixture has the following mass basis composition 35% co2, 50% hydrogen, and 15% nitrogen. The gas at 900 kPa and 100 C expanded to 300 kPa and 40C in a closed system containing 2 kg of the mixture. Determine the composition on molar basis, the initial partial pressure of each gas, the molar mass of the mixture, and the change of enthalpy of the mixture.
