command option Iron used in building materials, and it comes in two isotopes 54 Fe and 56Fe. 54Fe has an atomic mass of 53.939615 amu and an abundance of 5.845%. The other isotope, 56Fe, has a abundance of 91.754%. The average atomic mass between these tow isotopes is 54.4753172 amu. Calculate the actual atomic mass of 56Fe.
