°C and a total pressure of 750 mmHg is 200 mL. What is the partial pressure of the oxygen gas?

To find the partial pressure of the oxygen gas, we need to subtract the vapor pressure of water from the total pressure.

The vapor pressure of water at 24°C is 22.4 mmHg.

Partial pressure of oxygen gas = Total pressure - Vapor pressure of water
Partial pressure of oxygen gas = 750 mmHg - 22.4 mmHg
Partial pressure of oxygen gas = 727.6 mmHg
