Problem: Naturally occurring cobalt consists of only one isotope, 59Co, whose relative atomic mass is 58.9332. A synthetic radioactive isotope of cobalt, 60Co, relative atomic mass 59.9338, is used in radiation therapy for cancer. A 1.7222 g sample of cobalt has an apparent "atomic mass" of 58.9901.Find the mass of 60Co in this sample.
