A sample of oxygen is collected over water at a total pressure of 592.2 mmHg at 27C. The vapor pressure of water at 27C is 26.7 mmHg. What is the partial pressure of O2?

***Please show steps

  • Chemistry -

    Dalton's Law of partial pressure tells us that Ptotal = pO2 + pH2O.

  • Chemistry -

    How do you find pressure in this case ?

  • Chemistry -

    Read the problem.
    Ptotal = 592.2 mm
    pO2 = 26.7 mm
    You're making this a lot harder than it is.
    592.2 = 26.7 + pO2
    pO2 = 592.2-26.7 = ?
