Question 5 1 pts An element, X has an atomic number 60 and a atomic mass of 166.581 u. This element is unstable and decays by ß- decay, with a half life of 2.9d. The beta particle is emitted with a kinetic energy of 3.9 MeV. Initially there are 7.53x1012 atoms present in a sample. Determine the initial activity of the sample (in uCi).
