Question regarding victor meyer method

  1. Oct 16, 2012 #1
    1. The problem statement, all variables and given/known data
    I have this equation used for our experiment, which was Weiser's modification of the Victor Meyer method. Can someone help me understand this equation?



    2. Relevant equations
    http://postimage.org/image/mzmj5ammj/f7e660f1/ [Broken]


    Vs = standard volume
    V= experimental volume
    t = room temp
    P= barometric pressure
    h=height of water meniscus
    w=vapor pressure of water at the specified room temp




    3. The attempt at a solution
    1) why take the ratio of the triple point of water (or melting point?) to the room temperature?

    2) i understand that the correction for barometric pressure is given by the third multiplier. why h/13.6, what is this quantity?? 13.6 is the specific gravity of mercury, btw

    Hard to say anything seeing just a tiny fraction of the formula.

    Temperature ratio is there to convert t to kind of an absolute scale.
