(adsbygoogle = window.adsbygoogle || []).push({}); 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).
