Method/Apparatus/Procedure:
An all-glass apparatus was used. The system was equilibrated by bubbling gas through thermostatted water.
The solubility was measured in two different ways: by considering the amount of dissolved gas which disappeared from the vapor phase, and by volumetric analysis of the gas removed from a liquid solution sample.
