I have atmospheric concentration data of CO in microgram/m3. Is there a way to convert it in mass (kg) or find out the amount of carbon in kg from it?
For CO
1 ppb = 1.145 µg/m3
Mass and volume relation
1 mole-22.4 lit.
1 mole of CO=28 gram at STP.
In 28 kg of CO, C contains 12 Kg.
In General
µg/m3 = (ppb)*(12.187)*(M) / (273.15 + °C) where M is the molecular weight of the CO. An atmospheric pressure of 1 atmosphere
Prem Baboo Thank you Sir for your reply. I just wanted to clarify, I have CO concentration data in microgram/m3 unit. I want to convert it to Kg CO. Is it possible?
Not possible,
these are both micro gram and kg are mass(micro gram per m3 is density)
1 µg/m3 = 10-9 kg/m3 (1 e-9)
For all questions related to the units used in air pollution studies please kindly consult the classical textbook:
ATMOSPHERIC CHEMISTRY AND PHYSICS From Air Pollution to Climate Change SECOND EDITION
It is even possible to find a pdf file with this book after a Google search with the keywords:
seinfeld atmospheric chemistry and physics pdf
All relevant information is provided in section 1.6 on page 12; I strongly recommend this text considering your research activities.
