   2  Calculated by compiler using a gas molar volume at a temperature of 310.65 K and a pressure of 101.325 kPa of 25360 cm3 /mole.

 Method/Apparatus/Procedure:
   A glass bubbling-type of saturator immersed in a constant temperature bath was used. The gas was presaturated with water vapor. A known volume of saturated solution was transferred over mercury into a Van Slyke desorption apparatus. Gas removed in three evacuations was transferred to a sample tube where the volume was determined and a sample of the gas was analyzed. The solubilities were expressed as the Bunsen coefficients.

 Source and Purity of Materials:
   1. Ethene source and purity not given.
   2. Water distilled.

 Estimated Errors:
   Solubility: δβ/β = ± 0.04 (Complier)
   Temperature: δT/K = ± 0.05
