The two naturally occurring isotopes of antimony, 121 Sb ( 57 .... | Filo

SOLVED:Antimony has two stable isotopes, ^121 Sb and ^129 Sb, with masses of 120.9038 u and 122.9042 u, respectively. Calculate the percent abundances of these isotopes of antimony.

There are only two naturally-occurring stable isotopes of antimony. The mass and natural abundance of one of them are listed in the table below. Use whatever data you need from the ALEKS Periodic Table to determine the identity, mass, and natural abundance of the other isotope, and complete the table.Round your entry for mass to the nearest whole number and your entry for natural abundance to two significant digits.Mass (amu) Natural Abundance120 40W 21%Isotope M
