lodine is 80% ^127I, 17% ^126I, and 3% ^128I. Calculate the average atomic mass of iodine and show work completely.
Final answer:To calculate the average atomic mass of iodine, multiply the mass of each isotope by its percentage abundance and add up the results. The average atomic mass of iodine is 101.8 amu.Explanation:To calculate the average atomic mass of iodine, we need to multiply the mass of each isotope by its percentage abundance, and then add up the results. For iodine, the isotopes and their respective percentages are:^127I: 80%^126I: 17%^128I: 3%Using these values, we can calculate the average atomic mass:(0.80 x 127) + (0.17 x 126) + (0.03 x 128) = 101.8So, the average atomic mass of iodine is 101.8 amu....
