The results taken from a mass spectrum of chlorine gas show peaks at m/z 35.00 and m/z 37.00 (The m/z peaks on a mass spectrum identify the different isotopes of an element that are present in the sample). (a) Given that the relative abundances of Cl 35.00 and Cl 37.00 are 77.50% and 22.50% respectively, calculate the average relative atomic mass of chlorine atoms to four
