Given:
V (air) = 100 m ^ 3
φ (O2) = 21%

Find:
V (O2) -?

Solution:
The volume fraction of a gas shows how much a given gas takes from the total volume of the mixture. The volume fraction of oxygen in the air is 21%.
1) Calculate the O2 volume:
V (O2) = φ (O2) * V (air) / 100% = 21% * 100/100% = 21 m ^ 3.

Answer: The O2 volume is 21 m ^ 3.
