the pressure of a mixture of nitrogen,carbon dioxide and oxygen is 150 kPa.Wat is the partial pressure of oxygen if the partial pressures of the nitrogen and carbon dioxide are 100 kPa and 24 kPa,respectively?
To find the partial pressure of oxygen in the mixture, we can subtract the sum of the partial pressures of nitrogen and carbon dioxide from the total pressure of the mixture.
Partial pressure of oxygen = Total pressure of the mixture - (Partial pressure of nitrogen + Partial pressure of carbon dioxide)
Given:
Total pressure of the mixture = 150 kPa
Partial pressure of nitrogen = 100 kPa
Partial pressure of carbon dioxide = 24 kPa
Let's substitute the values into the formula:
Partial pressure of oxygen = 150 kPa - (100 kPa + 24 kPa)
Now we can simplify the expression:
Partial pressure of oxygen = 150 kPa - 124 kPa
Partial pressure of oxygen = 26 kPa
Therefore, the partial pressure of oxygen in the mixture is 26 kPa.
To find the partial pressure of oxygen in the mixture, you need to subtract the partial pressures of nitrogen and carbon dioxide from the total pressure.
Partial pressure of oxygen = Total pressure - partial pressure of nitrogen - partial pressure of carbon dioxide
Partial pressure of nitrogen = 100 kPa
Partial pressure of carbon dioxide = 24 kPa
Total pressure = 150 kPa
Partial pressure of oxygen = 150 kPa - 100 kPa - 24 kPa
Partial pressure of oxygen = 26 kPa
Therefore, the partial pressure of oxygen in the mixture is 26 kPa.
Hi january,
Dalton's Law of partial pressures states that P(total) = P(1) + P(2) + P(3) +....+ P(n) where 1, 2 and 3 are gases in the mixture.
So applying the law 150kPa = 100kPa + 24kPa + P(oxygen)
Hope I helped! (:
