Question 5 0/1 pts An element, X has an atomic number 41 and a atomic mass of 132.790 u. This element is unstable and decays by B decay, with a half life of 54d. The beta particle is emitted with a kinetic energy of 11.86MeV. Initially there are 9.90x1012 atoms present in a sample. Determine the activity of the sample after 118 days (in uCi). red 14.6 wer 8.7407 margin of error +/- 1%
