8.10 days/ 2.70 days = 3 half-lives; divide 100 by 2, three times to get 12.5 g left after 3 half-lives

Radioactive gold-198 is used in the diagnosis of liver problems. 198Au decays in a first-order process, emitting a β particle (electron). The half-life of this isotope is 2.7 days. You begin with a 5.6-mg
