100%
For my lab I had to find the unknown concentration of a solution. I found wavelength max of the potassium chromate. Then used that max to find the absorbtion for my sample dilutions. Based on my attached graph. Is my unknown concentration # making sense? Or did I make an error with the absorbance I wrote down in the lab. I did my calculations when I got home. They are correct, but my unknown concentration amount doesn't look like it will even be on the graph. Or am I wrong. Please advise and explain. Thank you
