Question

If you had a 20 gallon container and you filled it with air from the atmosphere, how many gallons of oxygen would there be in that container?

Answer 1

4.2 GALLONS

Step-by-step explanation:

Air is made up of nitrogen, oxygen, argon, carbon dioxide, neon, helium, krypton, hydrogen, and xenon.

the percentage of oxygen in the air is 21%

If a container has 20 gallons of air in it, oxygen in it = 0.21 x 20 = 4.2 gallons
