Where can I find coefficients to calculate ideal gas heat capacities for psuedocomponents from critical pressure, critical temperature and molecular weight?

Your question is not clear to me. Ideal gas pv=nRT
Ideal gas heat capacities will be solely dependent upon specific heat variation with temperature.
How does pseudo critical enter into this?

The pseudocomponents are "lumps" of components (usually heavy ends) and the critical properties of the psuedocomponents are determined in the lab. I need to calculate ideal gas heat capacity/enthalpy for the "lump" to get to the enthalpy departure. I think the GPA has some sort of correlation to predict the ideal properties from the critical properties and the MW but I can't remember where to find it. It may be a "senior" moment or a "blonde" moment but I'm stumped at the moment.
