Method/Apparatus/Procedure:
   Calibrated borosilicate glass cells were used in two sizes: 12-cm³ for pressures to 70 atm and 5-cm³ for pressures from 70-100 atm. The cell was initially almost filled with solvent then evacuated to the solvent vapor pressure. The initial solvent volume was obtained. Gas was volumetrically charged from a high pressure reservoir by displacement with mercury. Gas absorption was facilitated using a magnetically actuated stainless steel ball. At the highest pressure the cell was essentially completely filled with solution. The change in solution volume was noted with each increment of gas. The corresponding gas phase compositions were obtained using separate experiments and measuring the small volume of solvent necessary to saturate the gas. Details in Ref. 1.

Source and Purity of Materials:
   1. Ethene was from Matheson; purity 99.5%. Gas dried at 50 atm pressure using silica gel.
   2. Chloroform was the spectro grade from Matheson Coleman Bell; no purity given.

Estimated Errors:
   Solubility: δ x₁/x₁ = ± 0.01
   Temperature: δT/K = ± 0.07
   Pressure: δP/P = ± 0.01
