![SOLVED: Iron exists in nature as a mixture of predominantly three isotopes: ⁵⁴₂₆Fe (53.94 amu), ⁵⁶₂₆Fe (55.93 amu), and ⁵⁷₂₆Fe (56.94 amu). If the most common isotope, ⁵⁶₂₆Fe, accounts for 91.75% of SOLVED: Iron exists in nature as a mixture of predominantly three isotopes: ⁵⁴₂₆Fe (53.94 amu), ⁵⁶₂₆Fe (55.93 amu), and ⁵⁷₂₆Fe (56.94 amu).
