This aim of this paper is to predict fugacity coefficients from newly developed equations of state. The fugacity coefficients have been calculated for Methane and Caron di-oxide from equations of state of Soave Redlic Kwong (SRK), Peng Robinson (PR) and Twu Sim Tassone (TST) taking reduced temperatures, T r of interest from each of the three ranges 0< T r <1, 1< T r <3 and 1 <T <5.5 together with the reduced pressures, P r in steps of 0.2 in the range 0 <P <10. The calculated results of fugacity coefficients were compared with the available fugacity coefficient data for Beattie-Bridgeman (BB) equation. The calculations suggest that the TST equation of state is most suitable in predicting the fugacity coefficient of pure substances.
