    1. The problem statement, all variables and given/known data

    Determine the response factors for both Na and K with the Li internal standard

    Concentration Ratio
    Na : K : Li (in ppm)
    5.0 : 5.0: 500
    -------------------

    Signal Ratio
    Na : K : Li (relative units)
    4.9 : 6.4: 36.2

    2. Relevant equations

    Ax/x = F(As/s)
    Ax = Absorbtion signal of analyte
    x = concentration of analyte
    F = response factor
    As = absorbtion signal of standard
    s = concentration of standard

    3. The attempt at a solution

    Calculation for Na

    (4.9)/(5.0) = F [(36.2)/(500)]
    F = 13.5

    Calculation for K

    (6.4)/(5.0) = F [(36.2)/(500)]
    F = 17.7

    Seems simple enough right? So I was hoping that someone would be able to tell me if this is correct or incorrect because I have a funny feeling I did something strange (problem was too easy).
