At 273 K, you collect 0.5 L of oxygen over water that has a total pressure of 22 kPa.
What is the partial pressure of oxygen?
(The partial pressure of water vapor at 273 K is 0.61 kPa .)
Question 13 options:
273.61 kPa
21.39 kPa
36.07 kPa
22.61 kPa
To determine the partial pressure of oxygen, we need to subtract the partial pressure of water vapor from the total pressure.
Partial pressure of oxygen = Total pressure - Partial pressure of water vapor
Partial pressure of oxygen = 22 kPa - 0.61 kPa
Partial pressure of oxygen = 21.39 kPa
Therefore, the partial pressure of oxygen is 21.39 kPa. Answer: 21.39 kPa.
