Devise a general method for determining 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 how you will use the measurements to obtain the fractional abundances. vitemoniaco? absM bas pogotoal themingle A violatos- 2115 s.70.9992 * WH 20 2. a.
