General, Organic and Biological Chemistry An Integrated Approach [EXP-50957]

One use of positron emission tomography, or PET (Chapter 2), is to study cerebral blood flow. In this particular application, fluorine-19 is used as the positron emitter. After being artificially produced, $^{19}F$ is incorporated into $CH_{3}$ $^{19}F$ , which is then administered to the patient undergoing the PET scan. The $CH_{3}$ $^{19}F$ molecule is produced by the reaction

^{19}F^{-} + CH_{3}I \longrightarrow CH_{3} ^{19}F + I^{-}

If the theoretical yield for a synthesis of $CH_{3}$ $^{19}F$ is 3.66 μg, but 3.15 μg are obtained, what is the percent yield?
