A gas is collected over water at 20 degrees Celsius at a pressure of 752 mm. What is the pressure of the pure gas?

  • chemistry -

    At the conditions listed
    Ptotal = pgas + pH2O vapor. You need to look in your text and find the vapor pressure of H2O at 20C. That is pH2O. You know total P = 752 torr.
