gas mixture with a total pressure of 765 mmHg contains each of the following gases at the indicated partial pressures: 131 mmHg
CO2, 226 mmHg Ar, and 186 mmHg O2. The mixture also contains helium gas. what is the partial pressure of the helium gas
1 answer:
Answer:
322mmHg
Explanation:
To calculate the partial pressure of the helium gas, we use the Dalton’s law of partial pressure.
It states that for a mixture of gases which do not react, the total pressure is equal to the sum of the individual partial pressures.
This means that:
Total pressure = Partial pressure of CO2 + partial pressure of Ar + Partial pressure of O2 + Partial pressure of helium.
Hence, Partial pressure of the helium gas = 765-131-226-86 = 322 mmHg
