Explanation Given Amount of mixture of the sample = 3 .458g Amount of precipitated extract = 0 .474 mL Sodium sulphate (Na 2 SO 4 ) does not react with Sodium hydroxide (NaOH) . Therefor the reaction of Aluminium sulphate with sodium hydroxide Al 2 ( SO 4 ) 3 ( aq ) + 6NaOH ( aq ) → 2Al ( OH ) 3 ( s ) + 3Na 2 SO 4 ( aq ) The reaction for heating of the precipitate is, 2Al ( OH ) 3 ( s ) → Δ Al 2 O 3 ( s ) + 3H 2 O ( g ) Using mass of Aluminium Oxide from the last step, moles of Aluminium present has calculated

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
