Method/Apparatus/Procedure:
The solvent was held in a jacketed burette. Constant temperature water was circulated through the jacket. Gas was bubbled through the solvent until saturated. The dissolved gas content was determined by an electrometric dead-stop titration technique which yielded the bromine number. The electrometric titrator was based on a design given in [1].
Source and Purity of Materials:
- Ethene prepared by catalytic dehydration of ethanol over activated alumina at 350-400°C and analyzed by chromatography. Purity not given.
- 1-Butanol was treated for the removal of aldehydes and ketones and then distilled twice in a packed column.
Estimated Errors:
Mass concentration (m/v) (1): δx1/x1 = ±3% (Estimated by compiler)

Experimental Data
Gas molar volumes of 23910, and 24330 cm3/mole were used for the temperatures 293.15 K, and 298.15 K, respectively, and for a pressure of 101.325 kPa when calculating L.
It was confirmed by private communication with Dr. Nageshwar that x was for a total pressure of one atmosphere.
| $T$ ($\pu{K}$) | $T$ (°C) | $x_{1}$ | $L$ |
|---|---|---|---|
| 293.15 | 20 | 9.50 x 10-3 | 2.52 |
| 298.15 | 25 | 8.64 x 10-3 | 2.32 |
(1) Calculated by compiler. It is assumed that the mole fraction solubility, x, as originally given, is for a total pressure of 101.325 kPa although not specifically so stated in the paper. The mole fraction solubility is calculated for a partial pressure of 101.325 kPa.
