Answer:
Pressure of the Oxygen gas collected over water at 23.5°C = 728.35 mmHg = 0.958 atm
Step-by-step explanation:
The gas collected over water will mix with water vapour.
The total pressure of the setup is then a sum of the partial pressure of the gas collected over the water and the vapour pressure of water at the temperature given.
Total Pressure = (Partial Pressure of Oxygen) + (Vapour Pressure of water at 23.5°C)
Total Pressure = 750 mmHg
Partial Pressure of Oxygen = ?
Vapour Pressure of water at 23.5°C = 21.6472 mmHg from literature
750 = (Partial Pressure of Oxygen) + 21.6472
Partial Pressure of Oxygen = 750 - 21.6472 = 728.3528 mmHg = 0.958 atm
Hope this Helps!!!
