4-2. A liquid hydrocarbon mixture was made by adding 295 kg of benzene, 289 kg of toluene and 287 kg of p-xylene. Assume there is no change of volume upon mixing, i.e., 0 mix V = , in order to determine: 1. The species density of each species in the mixture. 2. The total mass density. 3. The mass fraction of each species. 4-2. This mixing process is analogous to the process illustrated in Figure 4-1 except for the fact that . If we let species A represent benzene, species B represent toluene, and species C represent p-xylene, the three species densities are given by 0 mix V ∆= (1) oo /, / AA A BB B CC C VV ρ= ρ ρ ρ o in which the total volume V is given by A B VVV C V = ++ (2) We can also write Eq. 1 in terms of the masses of the three components
