Based onVirialEquationofState(V-EOS),athermodynamicmodelwasdevelopedinthisstudy.The
applicability andperformanceofproposedmodified-VirialEOS(mV-EOS)wereassessedforcalculation
of thermodynamicpropertiesofhydrogenandthenextendedtothehydrogencontainingmixtures.For
comparison purpose,anumberofcubicequationsofstatewereused.Fourstatisticalparameterswere
