120 ml of oxygen gas was collected over water at a barometric pressure of 732.0 torr and 23 degrees celsius. what is the partial pressure of the oxygen?

2 answers

Ptotal = PO2 + PH2O
Ptotal = 732.0 torr.
pH2O = vapor pressure H2O (look in tables in your text) @ 23 degrees C.
Solve for PO2.
i have no idea bro. i wish i can do it to let every one now the answer.
