🤓 Based on our data, we think this question is relevant for Professor Stollenz's class at KSU.
(1) Calculate rate (k) at first order
k = 3.60x10-3 hrs-1
(2) t = 8 AM to 7 PM the next day = 35 hours
Initial mass = 2.5 µg
At 8:00 A.M., a patient receives a 2.5 µg dose of I-131 to treat thyroid cancer. If the nuclide has a half-life of eight days, what mass of the nuclide remains in the patient at 6:00 P.M. the next day? (Assume no excretion of the nuclide from the body.)
