the oxygen produce was colleced by displement method at (22c)at a total pressure of (754torr)the vapor pressure of water at (22c) in (21torr) calculate the pershel pressure of oxygen in the collected
To calculate the partial pressure of oxygen in the collected sample, you need to subtract the vapor pressure of water from the total pressure.
Given:
Total pressure (Ptotal) = 754 torr
Vapor pressure of water at 22°C (Pwater) = 21 torr
Partial pressure of oxygen (Poxygen) = Ptotal - Pwater
Poxygen = 754 torr - 21 torr
Poxygen = 733 torr
Therefore, the partial pressure of oxygen in the collected sample is 733 torr.
