For a binary mixture of 35%(mol)n-butane (1) and 65%n-hexane (2) at 373K, determine the fugacity coefficient of each component at 1, 10 and 15 bars. Use the truncated form of the virial equation of state. Zmix=1+RTBmixP;Bmix=i=1kj=1kyiyjBij First derive expressions for i using the given EOS. Data: At 373K, the second virial coefficients for this system are B11=422cm3/mol, B22=103.1cm3/mol,B12(B21)=650cm3/mol
