Fluorine-18 is a radioactive isotope use in a variety of medical imaging procedures including positron emission tomography (PET) scans. Fluorine-18 decays by positron emission with a half-life of 1.83 hours. A medical sample containing 18F has an activity of 4.00 millicuries. How many picograms of 18F are present in the sample? The atomic mass of 18F is 18.00 g/mol. (1 picogram = 1×10–12g 1 Curie = 3.7×10–10 decays/sec 1 millicurie = 1×10–3 Curies)
