A certain radioactive isotope has a lifetime of 343.6 s.Suppose you have a beam made of radioactive ions of this isotope travelling at 5.21 * 107 m/s in the laboratory,circulating in a cyclotron.If you begin with a sample of 2.50 micro-moles of this isotope,how many atoms have you left after one hour?
A) 4.97 * 1013
B) 4.23 * 1013
C) 3.61 * 1013
D) None are correct.
