Method/Apparatus/Procedure:
An all glass apparatus was used. The gas was bubbled through water kept in a constant temperature bath until equilibrium was reached.
After equilibration a liquid sample was volumetrically analyzed for its CO2 content.
The volume of the solution was pycnometrically determined at the temperature of the measurement.
