2. A 0.5 m³ tank holds a two-phase liquid-vapor mixture of carbon dioxide (CO₂) at -17 °C. The quality of the mixture is 0.6. For saturated carbon dioxide at -17°C, vf = 0.983 × 10-³ m³/kg and vg = 1.756 × 10-² m³/kg. Determine: (a) the specific volume of the two-phase CO₂ as a closed system; (b) determine the total mass of the CO₂; (c) determine the mass of saturated liquid and the saturated vapor, respectively; (d) determine the physical volume of the vapor and the physical volume of the liquid, respectively; (e) determine the ratio of the physical volume of the vapor to that of the liquid. This ratio should reflect the fact that the liquid occupies only a very small fraction of the total physical volume of the tank. Show full steps; carry all units.

Q8/A two-phase liquid-vapor mixture of a substance has a pressure of 150 bar and occupies a volume of 0.2 m³. The masses of saturated liquid and vapor present are 3.8 kg and 4.2 kg, respectively. Determine the mixture specific volume in m/kg.
