| **Determine the volume fraction of oxygen in its mixture with carbon dioxide, if 2 liters of oxygen and 4 liters of carbon dioxide were mixed (the gases were mixed under the same conditions)**

Given:

V (O2) = 2 l

V (CO2) = 4 l

To find:

φ (O2) -?

Solution:

1) Find the volume of the mixture of O2 and CO2 gases:

V mixture = V (O2) + V (CO2) = 2 + 4 = 6 liters;

2) Find the volume fraction of O2 in the mixture:

φ (O2) = V (O2) * 100% / V mixture = 2 * 100% / 6 = 33.3%.

Answer: The volume fraction of O2 in the mixture is 33.3%.
