devise a general method for determing the fractional abundances of two or more isotopes from a mass spectrum. Your method must include some means of measuring the signals. You must state the type of measuring device that you will need to apply your method. You must also indicate hoq you will use the measurements to obtain the fractional abundances.

twinkles · Answer

he sum of the heights of all 3 isotopes would be 62+2+8 = 74 

The fractional abundance of 20-Ne 2ould be 62/74 = 0.861. 

You can just divide the height of each of the other isotopes by the total height to get their relative abundances.
