Determine the partial pressure of oxygen collected by water displacement if the water temperature is 20.0

C and the total pressure of
the gases in the collection bottle is 760 torr.
PH2O at 20.0

C is equal to 17.5 torr.

  • Chemistry -

    Ptotal = pO2 + pH2O
    Ptotal = 760 torr
    pH2O = 17.5
    pO2 = ?

  • Chemistry -

    so you get your 760 torr because that is your total and you subtract your 17.5 torr and you get 742.5 and that is your pO2
