Question #4856
I have a little question.
A mixture of CO2 and N2 gases has an experiment density of 21922 mol/m3 at T=225K and Pressure= 68.759 MPa and Z=1.67661. What is density of this mixture of gases in mol/m3 by Peng-Robinson equation of state? (Mole fraction of Co2= 10.56%)

Expert's answer
Using Peng-Robinson equation of state can be given by:
Z = PVm/RT
Vm - molar volume of gases mixture
Hence, density in mol/m3 can be given by:
ρ = 1/Vm = 1/(4.5614×10-5) = 21923.094 mol/m3
Z = PVm/RT
Vm - molar volume of gases mixture
Hence, density in mol/m3 can be given by:
ρ = 1/Vm = 1/(4.5614×10-5) = 21923.094 mol/m3
