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)
