The atomic mass you see in the periodic table is a weighted AVERAGE of the isotopes according to their percent abundance.
(191.0*0.3758)+ (193.0*0.6242) = ??
Calculate the atomic mass of iridium. Iridium has two isotopes. Iridium-191 has a mass of 191.0 amu and a percent abundance of 37.58%. Iridium-191 has a mass of 193.0 amu and a percent abundance of 62.42%.
