With this definition of the partial molar excess Gibbs free energy and the activity coefficient, the fugacity of a species in a liquid mixture can be computed from: (55)f¯iL(T,P,x)=xiγi(T,P,x)fiL(T,P) where the fugacity of the pure component is equal to the vapor pressure of...
Let the mass of each gas present in the mixture be mi. Then the mass balance gives the total mass of the mixture mm as (12.1)mm=m1+m2+⋯+mN=∑i=1Nmi The corresponding number of moles ni of gas i with molecular mass Mi can be determined from Eq. (1.9) as (1.12)ni=mi/Mi ...
