WebTo get the abundance of each isotope, you could use a tool called a mass spectrometer. Basically how it works is that you have a stream of ionized atoms of one element. Then, you use a magnet to try and kick them out of their path. The ones that are the heaviest will be pushed less, and the lighter ones will be pushed more. WebFeb 13, 2014 · Mass of 10 000 atoms of Cl = 354 500 u Average mass of a Cl atom = (354 500 u)/ (10 000 atoms) = 35.45 u The more abundant an isotope, the closer the atomic mass will be to the atomic mass of that isotope. Since Cl-35 is more abundant, the average atomic mass will be closer to 35 than to 37. Answer link
