257.05 x 10-23.823.52 x 10-3
 Method/Apparatus/Procedure:
   A 1 to 15 volume ratio mixture of heavy water and bromoethane was introduced into an equilibration flask and then lowered into the waterbath thermostat. The assembly was shaken mechanically for about 90 minutes at constant temperature. The amount  of heavy water in the organic phase was determined by a modified Karl Fischer titration. The determination was done in triplicate. The description of the procedure was taken from a secondary source.1 The original university  report is no longer available.

 Source and Purity of Materials:
   (1) Source and purity not given.
   (2) Source not given, purified and dried before use.

 Estimated Errors:
   Solubility: ± 5.0 × 10–5 av. dev.
   Temperature: ± 0.05 K.
