Question

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

Answer 1

[AI-generated answer — Bot GPT 3.5]

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.
