Variables:

Room Temp: 293.15 - 303.15 $\pu{K}$
Pressure: 40.0 - 112.0 $\pu{kPa}$

Method/Apparatus/Procedure:

Volumetric method. The apparatus is described in detail in the source. The $\ce{CO2}$ was purified in the line and sublimed into the system. Mercury levels were read with a cathetometer to ± 0.05 mm. Atmospheric pressures were read to ± 0.1 mm with a mercury barometer and were corrected to 0 °C. The volumes determined were reproducible to ± 0.02 mL.

Source and Purity of Materials:

1. Commercial; purity 99.9%.
2. Fisher Certified Reagent. Purity better than 99.3%.
3. Fisher Certified Reagent. Purity better than 99.3%.
4. Purified. Source not specified.
5. Conductivity water, distilled from a quartz still.
   Conductivity less than $\pu{1E-7 \Omega\,-1 m-1}$.

Estimated Errors:

Ambient temperature: δT/K = ±0.05 (authors)
Mass concentration (m/v) (1): δα = ±1.1% (authors)
