Examen Gas

1. The document contains component mole fractions, critical properties, and parameters for the Peng-Robinson equation of state calculations for a gas mixture. 2. Iterations of the Peng-Robinson equation are shown to calculate the compressibility factor with decreasing error at each step. 3. The calculations result in a compressibility factor of 0.71185062 which matches the literature value from Wichert and Aziz within an acceptable tolerance.
