- P1A.6 The molar mass of a newly synthesized fluorocarbon was measured in a gas microbalance. is device consists of a glass bulb forming one end of a beam, the whole surrounded by a closed container. The beam is pivoted, and the balance point is attained by raising the pressure of gas in the container, so increasing the buoyancy of the enclosed bulb. In one experiment, the balance point was reached when the fluorocarbon pressure was 327.10Torr; for the same setting of the pivot, a balance was reached when CHF3 (M = 70.014 g mol−1) was introduced at 423.22 Torr. A repeat of the experiment with a di erent setting of the pivot required a pressure of 293.22 Torr of the uorocarbon and 427.22 Torr of the CHF3. What is the molar mass of the fluorocarbon?

When the mixture reaches equilibrium, the temperature of the mixture is 73 °C. The gases can be assumed to be ideal gases.

- 3. A gas contained within a closed piston-cylinder assembly undergoes three processes in series: Process 1-2: Constant volume from P₁ = 1 bar, V₁ = 4 m³ to state 2, where P₂ = 2 bar; Process 2-3: Compression to V3 = 2 m³, during which the pressure-volume relationship is PV = constant; Process 3-4: Constant pressure to state 4, where V4 = 1 m³; (a) Sketch the processes in series on P-V coordinates.

- Producer gas is a fuel that is manufactured from the reaction of coal, steam and air. A producer gas has the following composition by volume (dry basis): 20.35% CO, 11.03%, CO2, 15% H2, 51.43% N2, 1.98%O2 and 0.21 % CH4. The gas is flowing at 6000 cfm. It has a temperature of 200℃ , a pressure of 21 cm Hg and a partial pressure of 50 mm Hg for H2O. The atmospheric pressure is 758 mm Hg.
