(a) Interpretation: The percentage of spherical atoms on surface of the cubic nanoparticle of edge-length 5.0 nm is to be calculated. Concept introduction: Nanotechnology is a field that studies the atoms and molecules on the nano-scale. Nano is a prefix used for 10 − 9 times of meter scale. In the nano regime, the properties of compounds change drastically from that of bulk. These unique properties of nanoparticles are due to the higher ratio of surface area to volume and charge to mass.

1. Calculate the accurate monoisotopic mass (using all 1H, 12C, 14N, 160 and 35CI) for your product using the table in
your lab manual. Don't include the Cl, since you should only have [M+H]*. Compare this to the value you see on
the LC-MS printout. How much different are they?
2. There are four isotopic peaks for the [M+H]* ion at m/z 240, 241, 242 and 243. For one point of extra credit,
explain what each of these is and why they are present.
3. There is a fragment ion at m/z 184. For one point of extra credit, identify this fragment and confirm by
calculating the accurate monoisotopic mass.
4. The UV spectrum is also at the bottom of your printout. For one point of extra credit, look up the UV spectrum
of bupropion on Google Images and compare to your spectrum. Do they match? Cite your source.
5. For most of you, there will be a second chromatographic peak whose m/z is 74 (to a round number). For one
point of extra credit, see if you can identify this molecule as well and confirm by…
Please draw, not just describe!
can you draw each step on a piece of a paper please this is very confusing to me
