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 ± 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 (0.5-1.5g) the solvent content of the gas phase was obtained.

Source and Purity of Materials:
   1. Ethene contains 2.9% ethane.
   2. Cyclohexane properties given as:
Density at 20 °C = 0.7801 g/cm3
nD20 = 1.4271
Normal boiling point = 80.9 °C

Estimated Errors:
   Solubility: Original data: δ x1/x1 = ± 2%
Tabulated values: δx1/x1 = ± 4%
