3 15 Points In Truth The Mass Spectrometer Measures The Charge To Mass Ratio Not Specifically The Mass However Th 1 (37.25 KiB) Viewed 27 times

3. (15 points) In truth, the mass spectrometer measures the charge-to-mass ratio, not specifically the mass. However, the difference between a differently ionized species of the same molecule is rather mundane, as are the differences between separate isotopes of the same atom, compared to different atoms all together. (a) (5 points) You have a gas of single oxygen atoms which can be singly, doubly, or triply ionized. Your mass spectrometer will therefore measure three spots on the detector screen. By what factor is each of these separated? In other words, what are the possible values of the ratio of separation distances? (b) (5 points) You also have differenct isotopes of oxygen: 160, 170, and 150. For a single ionization state, by what factor is each of the spots for different isotopes separated? In other words, what are the possible values of the ratio of separation distances? Page 2 (c) (5 points) Sketch what the spots on your detector screen will look like.
