An element, X has an atomic number 48 and a atomic mass of 113.309 U. This element is unstable and decays by ß decay, with a half life of 82d. The beta particle is emitted with a kinetic energy of 11.80MeV. Initially there are 4.48x1012 atoms present in a sample. Determine the activity of the sample after 140 days (in uCi). a 3.6276 margin of error +/- 1%
