It's Che 301:Chemical Engineering Thermodynamics course. Can you help me? I will rate your work. Thank you.

Problem 5 The triple point of Carbon Dioxide is at T =-56.57C and P=5.18bar . Calculate the fugacity of dry ice (solid CO2) in bar at T = -56.57C and P=100 bar. At the triple point assume that the vapor phase follows the Peng-Robinson EOS. The density of Dry Ice can be taken equal 35.492 kmol/m3
