Naturally occuring bromine (relative atomic mass = 79.9) consists of a mixture of two isotopes: 79Br and  81Br. Calculate the relative abundance of the naturally occurring isotopes of bromine.

 

 

see: https://en.wikipedia.org/wiki/Bromine

 

 

Natural abundance:

79Br  50.69%  79Br is stable with 44 neutrons

81Br  49.31%  81Br is stable with 46 neutrons
