Notes:
   ¹  Calculated by compiler for a partial pressure of 101.3 kPa assuming that the mole fraction ethene is equal to 1/H.

Method/Apparatus/Procedure:
   Solubilities were determined by a volumetric method described as "the Ostwald method". No other details given.

Source and Purity of Materials:
   1. Linde Co. sample, purity 99.8 volume per cent.
   2. Uvasol and analytical grade. Serlabo sample, purity 99 mole per cent.

Estimated Errors:
   Solubility: δH = ± 1.25% (estimated by compiler)
   Temperature: δT/K = ± 0.1 (estimated by compiler)
