  1. you need to find the pressure for water vapor for certain temperatures. this is given in a table and have been calculated for you.

    use the dalton's law of Partial pressure. i.e. the Pressure for the dry gas equals the Total pressure of the system - the pressure of water vapor for that temperature.

    hope that helps.
