Calculate the volume of oxygen in air with a volume of 19 m³
| March 14, 2021 | education
The volume fraction of oxygen in the air is 21% (from the reference book)
w (O2) = V (O2) / V (air)
w (O2) = 21% = 0.21
Let us express the volume of oxygen from the formula:
V (O2) = w (O2) * V (air), let’s subtract the numerical values:
V (O2) = 0.21 * 19 = 3.99 m³
