Solution: The half-life of 27Mg is 9.50 min. (a) Initially
Chapter 19, Problem 19.95(choose chapter or problem)
The half-life of 27Mg is 9.50 min. (a) Initially there were 4.20 3 1012 27Mg nuclei present. How many 27Mg nuclei are left 30.0 min later? (b) Calculate the 27Mg activities (in Ci) at t 5 0 and t 5 30.0 min. (c) What is the probability that any one 27Mg nucleus decays during a 1-s interval? What assumption is made in this calculation?
