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?

  • chemistry -

    Ptotal = PO2 + PH2O
    Ptotal = 732.0 torr.
    pH2O = vapor pressure H2O (look in tables in your text) @ 23 degrees C.
    Solve for PO2.
