   c  Calculated by the compiler. P = 1 atm = 101.325 kPa = 1.01325 bar

 Method/Apparatus/Procedure:
   Solution was made up by weight. Concentration of solution was verified by measuring the density. (Density was not reported in the paper.) A measured volume of gas was brought into contact with a measured quantity of gas-free solvent. Equilibrium was established by agitation using a magnetic stirrer. The volume of remaining gas was measured. The amount of gas absorbed was estimated from change in volume of gas. Details in original paper.

 Source and Purity of Materials:
   (1) From commercial cylinder. Purity 99.8 %.
   (2) Analytical grade.
   (3) Distilled and degassed.

 Estimated Errors:
   Solubility: δα = ± 2 %
   Temperature: δT/K = ± 0.2
