8.999×10^-2 ppmv is the concentration of ppmv of CO.
How to calculate concentration of ppmv CO?
Concentration is defined as amount of solute per amount of solution or solvent.
To convert from ppm by mass to ppm by volume, divide by the density of the particles.
Calculation:
The conc of CO = 103 mg/m³
=0.103 mg/m³ air
Molecular weight if CO = 28g/mol
Moles of CO = 0.103×10^-3 g/28g/mol
= 3.678×10^-6 mol
Calculate the volume of CO as follows:
V=nRT/P
=3.678×10^-6 mol × 8.314 Pa m³/mol K × 298.15 / 101325 Pa
= 8.999×10^-8 m³ CO/m³ air
Convert units of V into pmv as follows
=8.999×10^-8 m³ CO/m³ air ×10^6
=8.999×10^-2 ppmv
Or 0.08999 ppmv
