Find the natural abundance of sb -123
WebMar 31, 2024 · The average atomic mass of an element is calculated by doing the sum of the masses of all its isotopes, each is multiplied by its natural abundance (the decimal which is associated with percent of the atoms of that element that are of that particular given isotope). Converting percentages to fractions, we have ${f_1} = \dfrac{57.2}{100}= 0.572$ WebJul 7, 2024 · The element antimony has two stable isotopes, antimony-121 with a mass of 120.90 amu and antimony-123 with a mass of 122.90 amu.
