How do I change the concentration of a VOC CHCs in water (mg/L) to parts per million by volume in air after it has been stripped to become off-gas?

I have concentration data on the volatile chlorinated hydrocarbons (VOC CHCs) in the groundwater as mg/L. The VOC CHCs will be stripped from the groundwater by using an air stripper, hence, you get an off-gas waste stream that contains these VOC CHCs. From here, I would like to know how to get its concentration in the off-gas waste stream (mg/m3) so I could obtain its ppmv. This information is important for me so I could design a carbon bed adsorber. Can anyone help? Really appreaciate it.

Dear Md.Badriadib,

1000 L = 1 m3

1 mg/Lit = 0.001 mg/m3

1 mg/L = ppm

Relation of Mass & Volume 22.4 Nm3= 1 Kg. mole (STP,)

22.4 lit = 1 gram mole(STP)

385 ft3 = 1 lb mol (STP)

Regards,

Prem Baboo
