Spectrophotometric Copper Determination calculations
I am quite confused on how to do the calculations on my chemistry lab, i have scanned, and rewritten my answers so they would be more clear :-) . the
questions i have are on the 3rd and 4th image, im just really not sure how to do the calculations, if someone can show me how that would be great, i
can do the graph and all that, i'm just not sure how to do the calculations. thank you very much, the lab report is below. (note, if the images are to
small just keep clicking them, and they will open again, but larger)

Clearly this is 'do my homework for me' post and belongs in the 'Beginnings' section. There someone will probably give you some hints (but w/o giving
the precise answers).
W/o having scanned all of the exam forms, it boils down to being able to calculate concentrations of prepared solutions and applying the (simple)
Lambert-Beer Law on light absorbance correctly.
