Section 4.24-2. Determine the mass density, ?, for the mixing process illustrated in Figure 4-2.4-3. 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??mixV, 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.4-4. A gas mixture contains the following quantities (per cubic meter) of carbon monoxide, carbon dioxide and hydrogen: carbon monoxide, 0.5 kmol/m3, carbon dioxide, 0.5 kmol/m3, and hydrogen, 0.6 kmol/m3. Determine the species mass density and mass fraction of each of the components in the mixture.4-5. The species mass densities of a three-component (A, B, and C) liquid mixture are: acetone, , acetic acid, , and ethanol, . Determine the ollowing for this mixture: 3326.4 kg/m??A3326.4kg/m??B3217.6 kg/m??Cf1. The mass fraction of each species in the mixture.2 The mole fraction of each species in the mixture.3. The mass of each component required to make one cubic meter of mixture.4-6. A mixture of gases contains one kilogram of each of the following species: methane (A), ethane (B), ropane (C), carbon dioxide (D), and nitrogen (E). Calculate the following:1. The mole fraction of each species in the mixture2. The average molecular mass of the mixture4-7. Two gas streams, having the flow rates and properties indicated in Table 4.7, are mixed in a pipeline. Assume perfect mixing, i.e. no change of volume upon mixing, and determine the composition of the mixed stream in mol/m3.Table 4.7.
