I'm already familiar with this procedure, I wish I only had tested one solution but I had a series of dilutions so it makes it much more complicated since there is actually no correlation between the absorbance and the dilute. By my last phrase I mean that if I dilute by x10, I don't get a...

I think that we couldn't predict such high conc. of the original substances. Either way, I could use extrapolation to calculate the initial conc., but if these are the results we recieved, how can I still utilize them?

I do know the k value from the graphs, but I actually don't have any correlation between the results - if I calculate backwards to get to the initial conc. I get totally different results from each dilution. it doesn't make sense

Homework Statement Hello, This week I ran an AA Spectroscopy experiment in my university, in which we had to analyze the percentage of Copper in a metal coin, and the containment of Iron in morning cereal. We used 2 standard solutions of 1 and 10 ppm (containing both Copper and Iron), and...
