Interpretation: The relation between molar mass of a substance and atomic masses of the component atoms needs to be explained.
Concept Introduction: Mole concept is used to calculate the moles, mass, number of atoms and moles of a compound. The molar mass of a substance is the mass of 1 mole of substance. It is represented in g/mol. The relation between these values can be shown as:

Answer to Problem 18A
The molar mass of compound is the sum of
Explanation of Solution
Given information:
The molar mass of a substance and atomic masses of the component atoms are related to each other.
The molar mass of compound is the sum of atomic mass of the component atoms present in the given chemical compound.
Since a molecule is composed of different atoms which are bonded with each other through
The molar mass of compound is the sum of atomic mass of the component.

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).
