The concentration of Sulphur Dioxide (SO2) in ambient atmosphere was measured as 30 mg/m³. Under the same conditions, the above SO2 concentration expressed in ppm is ___. Given: P/(RT) = 41.6 mol/m³; where, P = Pressure; T = Temperature; R= universal gas constant; Molecular Weight of SO2 = 64.
-
- 3.0113 ppm
- 2.0113 ppm
- 0.0113 ppm
- 1.0113 ppm
Correct Option: C
0.0133
Given concentration of SO2 = 30 μg/m³
| 106 m³ of air has 30gSO2 = | = mol SO2 | |
| 64 |
| V = | = | ||
| p | p/RT |
| = | = 0.0113 m³ | ||
| 41.6 | mol/m³ |
Conc. of SO2 in ppm = 0.0113 ppm
