Iron exists in nature as a mixture of predominantly three isotopes: 5426Fe (53.94 amu), 562.Fe (55.93 amu), and 5726Fe (56.94 amu). If the most common isotope, 5626Fe, accounts for 91.75% of iron atoms, and the average atomic mass of iron is 55.85 amu, what is the percent abundance of the rarest of these three isotopes of iron?
