If I understood the question correctly, it asks about how one can calculate the total concentration of Iron if the analytical method used gives directly the concentratoin of Iron-54. WHat one would do in this case is obtain the abundance of iron-54 which happens to be 5.82% (reference is MERK INDEX). by obtaining the concentration vallues from the analytical method and calling it X, then Y which is the total conncentration of iron would be: (Y=X*100/5.8).
On the other hand to obtain the concentration of ...
