CONVERSION OF VOLUMETRIC ANALYSIS TO MASS (OR GRAVIMETRIC) ANALYSIS AND VICE-VERSA

Let the fraction of CO, CO₂, N_2, and O₂ by volume of dry exhaust gases by C₁, C₂, N, and O, respectively, obtained by the Orsat apparatus. The volumetric analysis can be converted into gravimetric analysis, as shown is Table 1.5.

Table 1.5 Conversion from volumetric to gravimetric analysis

Σ(4) = ΣX = 28 C₁ + 44 C₂ + 28 N + 32 O

The conversion from gravimetric to volumetric analysis is given in Table 1.6.
