# Mixed 16 liters of oxygen and 12 liters of carbon dioxide. Find the volume fraction of each gas in the resulting mixture. Given: V (oxygen) = 16 liters, V (carbon dioxide) = 12 liters.
Find: ϕ (oxygen) – ?, ϕ (carbon dioxide) -?
Decision.
1. Calculate the volume of the mixture:
V (mixture) = V (oxygen) + V (carbon dioxide) = 16 liters + 12 liters = 28 liters.
2. We calculate the volume fraction of oxygen in the mixture:
ϕ (oxygen) = V (oxygen) / V (mixture) = 16 l: 28 l = 0.5714, or,
multiplying this value by 100%, we get 57.14%.
2. We calculate the volume fraction of carbon dioxide in the mixture:
ϕ (carbon dioxide) = V (carbon dioxide) / V (mixture) = 12 L: 28 L = 0.4286, or 42.86%.
Answer: ϕ (oxygen) = 57.14%, ϕ (carbon dioxide) = 42.86%. Remember: The process of learning a person lasts a lifetime.
