Those who know how to calculate exhaust gas concentrations, please come in

What methods can be used to calculate this: Given that the **emission standard is 200PPM, how can the concentration of sulfur dioxide in the exhaust gases be determined?~~~~~~~
The total exhaust emissions are multiplied by 200PPM; after performing the unit conversion, the result gives the total amount of sulfur dioxide emitted in the exhaust gases.
Reply to 1# Cui Yunxuan: 200PPM refers to the concentration of sulfur dioxide in exhaust gases; what else needs to be taken into account? **The actual emission standard for sulfur dioxide in exhaust gases is 400 mg/Nm3, which is equivalent to 140 ppm.
What was said upstairs is correct – \"the actual standard for sulfur dioxide emissions from exhaust gases is 400 mg/Nm3, which is equivalent to 140 ppm.\" " Calculation method: Density of SO2 – 64/22.4 = 2.857; 400/2.857 = 140 ppm. Generally, if you know that the air flow rate through the chimney is 10,000 Nm3/h, then the SO2 emission amount is – 10,000*400*10-3*10-3 = 4 kg/h
