lodine-123 is a radioactive isotope used to study thyroid gland functions. It decays in a first-order process with a half life of 13.1 h. You receive a 10.00 g sample for some of your experiments, but you have to work fast before it is all gone. Calculate the number of hours it will take for 8.50 g of your sample to decay.
