Clean Dry Air Components Percent
N2 Nitrogen 78.0836
O2 Oxygen 20.9466
Ar Argon 0.9345
CO2 Carbon Dioxide 0.0325
Ne Neon 0.0018
He Helium 0.0005
All the rest 0.0005
This is an approximation
Clean = no particulate matter
Dry = no humidity
All the rest includes
Kr Krypton
SO2 Sulfur Dioxide
CH4 Methane
H2 Hydrogen
N20 Nitrous Oxide
Xe Xenon
O3 Ozone
NO2 Nitrogen Dioxide
I2 Iodine
CO Carbon Monoxide
NH4 Ammonia
This works except that you can not use
subscripts inside of a -pre-
Is there a way to use a fixed font like courier new?
