Method/Apparatus/Procedure:
The method is similar to that described by Sage and Lacey. Accurately known masses of solvent and gas were charged into an evacuated equilibrium vessel. The temperature was controlled to $\pu{pm 0.05 K}$. The volume occupied by the system in the equilibrium vessel was varied by forcing a definite amount of mercury into it from a graduated mercury supply vessel equipped with a movable electric indicator. Equilibrium was attained using an electromagnetic stirrer. The pressure was measured using pressure gauges. A sample of the gas phase was passed to a trap cooled to 213 K with acetone and dry ice. From a reading of a gas burette connected to the trap, the volume of ethylene was determined. From the increase in weight of the trap (0.5 - 1.5 g) the solvent content of the gas phase was obtained.
Source and Purity of Materials:
- Ethene contains 2.9% ethane.
- Cyclohexane properties given as: $\rho^{20} = \pu{0.7801 g mL-1}$; $n_{D}^{20}$ = 1.4271; BP = 80.9°C
Estimated Errors:
Mass concentration (m/v) (1): Original data: δx1/x1 = ±2%
Tabulated values: δx1/x1 = ±4%
