Calculate average atomic mass of Iron. Fe-54 has a mass of 53.9396 amu and an abundance of 5.845%. Fe-56 has a mass of 55.9349 amu and an abundance of 91.754%. Fe-57 has a mass of 56.9354 amu and an abundance of 2.119%. Fe-58 has a mass of 57.9333 amu and an abundance of 0.282%.

Fe-54: 0.05845 x 53.9396 = 3.15277

Fe-56: 0.91754 x 55.9349 = 51.32251

Fe-57: 0.02119 x 56.9354 = 1.20646

Fe-58: 0.00282 x 57.9333 = 0.16337

Avg atomic mass = 55.84511 amu
