Calculate The Mass Percentage Of Oxygen In Dry Air
Can you calculate the percentage of oxygen in dry air? 3
Air is a mixture of different gases. The 10 most common gases are listed here along with their molar parts and molar mass.
Molar component (g / mol)
Nitrogen 0.78084 28,013
Oxygen 0.20948 31.998
■■■■■ 0.00934 39.948
Carbon Dioxide 0.000375 44.0099
Neon 0.00001818 20.183
Helium 0.00000524 4003
0.000002 to 16.043
Krypton 0.00000114 83.80
Hydrogen 0.00005 2.0159
Nitrous oxide 0.0000005 44.0128
How many meters of carbon dioxide is present in 1.00 m
23.1%
Add first (molar fraction x mol M), you will see ■■■■■ of dry air m ~ 29.
Distribute Oxygen (Mرller Fraction x M mol) / 29 and you get 0.231135 ...
So, with Fig. 3: Oxygen in dry air is 23.1% per m2.
