Spectrophotometric Copper Determination calculations

  • #1
The template doesn't really work well for mine considering its a lab sorry ><. 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)
***as an added token of my appreciation i will give the first person to answer this a free demonoid account***(if wanted) just trying to give something back :-)

I was looking at your images to find any information about molar absorbtivity. I found none. What did I miss, if anything?
