DETECTIONHOW TO FIND ISOTOPIC ABUNDANCE?An analyzer called a mass spectrometer is used. The sampleis first vaporized and is then injected as a gas into an evacuatedchamber, where it is bombarded with a beam of high-energy electronsby which the sample in gas particles become positively charged ions.Some of them fragment into smaller ions while others remain a biggerions, surviving fragmentation. The various ions of different masses arethen accelerated by an electric field and passed between the poles ofa strong magnet, which deflects them through a curved, evacuatedpipe. The lighter ions defected more strongly than heavier ones.By varying the strength of the magnetic field, it is possible to focusions of different masses through a slit and onto a detector assembly.The mass spectrum that results is plotted as a graph of ion massversus intensity- the higher the spectrum, the more abundantthe ion of that mass.FaradaycollectorsMass 46--Mass 45-Mass 44-MagnetAmplifiers výýRaiooutputION SOURCEBeam focussinglon acceleratorElectron traplon repellerGas inflow (from behind)lonizing filamentA Sketch of a Mass SpectrometerQUESTIONA certain amount of a hypothetical monoatomicelement X was put into a mass spectrometer.And it generates the mass spectrum as follows:201021 MASS, amu23Hint: Remember the masses at 21 and 23 are analogous to 18-yr old and 19-yr old (or 20-yr old) in Question #2.

QUESTION A certain amount of a hypothetical monoatomic element X was put into a mass spectrometer. And it generates the mass spectrum as follows: 10 21 MASS, amu 23 Hint: Remember the masses at 21 and 23 are analogous to 18-yr old and 19-yr old (or 20-yr old) in Question #2. And the relative abundances at 10 and 20 are analogous to the number of students in each age group in Question #2. So apply the solution procedure of Question #2 to this question to find out the percentages of the first and the second sotopes. The two peak heights are the same. How many isotopes are present for this element X? The rough abundance of the first isotope in percentage is Relative Abundance 20
