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
