The graph below represents the mass of a particular isotope of iodine in a person's
body as a function of time. The initial mass decays to 5 mg after 16 complete days.
Mass
(mg)
|(0, 20)
(16, 5)
Time (days)
If the half-life of an isotope is the time it takes to decay to half its
mass, then the half-life of this isotope of iodine, in hours, is
approximately
