Antimony has 2 naturally occurring isotopes. The mass of antimony-121 is 120.904 amu and the mass of antimony-123 is 122.904 amu
Sav [38]
Wow, now this one is a hard one, took me quite a while to figure it out but here it is:
120.904(x)+122.904(1-x)=121.76 \\ 
120.904x-122.904x+122.904=121.76 \\ 
-2x+122.904=121.76 \\ 
-2x=-1.144 \\ 
x=.572  \\ 
1-.572=.428
The abundances of the two isotopes is:
Antimony-121 = 57.2%
Antimony-123 = 42.8%
