Variables:

Room Temp: 303.15 $\pu{K}$
Pressure: 101.325 $\pu{kPa}$
Amount concentration (2): 0 - 9.36 (M₂ mol/L) mol/L

Method/Apparatus/Procedure:

A 200 mL glass flask was connected to a pressure-measuring manometer by means of a horizontally mounted spiral tube. The spiral tube permitted the flask to be shaken with an amplitude of up to 2 cm for equilibration. The solvent (80-125 mL) was deaerated in the flask. The change in pressure of a known volume of gas was measured from which the solubility was determined. The total volume of the apparatus was initially determined by weighing the apparatus filled with distilled water. The 'distribution constant', $h$, was determined for pressures below 101.325 kPa. Method described in [1].

Source and Purity of Materials:

1. Ethene was from Matheson, purity 99.5%.
2. Perchloric acid was from Baker and was the CP grade.

Estimated Errors:

Ambient temperature: δT/K = ±0.01
Mass concentration (m/v) (1): δh/h = ±0.02
