A 0.050 mg dose of iodine-131 was administered to a patient to treat hyperthyroidism. What is the remaining mass after 32.4 days? The half-life of iodine-131 is 8.1 days.
Homework Answers
11) t = 32.4 days
t1/2 = 8.1 days
A = 0.050 mg
A0 = ?
t= ln( A0/A) X t1/2/0.693
32.4 = ln(A0/0.05) x 8.1/0.693
2.772 = ln(A0) - ln(0.05)
-0.224 = ln(A0)
A0 = 0.597 mg
