Half Life and Radioactivity Practice Problems. In these practice problems, we will work on the kinetics of radioactive reactions. Most often, in chemistry at least, you will be asked to determine the activity, quantity, the decay rate of radioactive isotopes, the time required to drop the activity to a certain level or apply ...
WebProblem #1:The half-life of Zn-71 is 2.4 minutes. If one had 100.0 g at the beginning, how many grams would be left after 7.2 minutes has elapsed? Solution: 7.2 / 2.4 = 3 half-lives (1/2)3= 0.125 (the amount remaining after 3 half-lives) 100.0 g x 0.125 = 12.5 g … WebSolution. We use the equation A t = ( 1 2) t t 1 / 2 A o, where A t is the activity in time t, A o is the original activity. 500 = ( 1 2) 10 t 1 / 2 × 6000. t 1 / 2 = 10 log 2 log 12. = 2. 789 h o u r s. We can also use the relation A t = ( 1 2) n A o, where n is the number of half-lives. A t = A o 2 n. n = t t 1 / 2 = l og A o A t log 2.
