1. The problem statement, all variables and given/known data Determine the mass defect of the nucleus for cobalt 5927Co, which has an atomic mass of 58.933 198 u. Express your answer in AMU and Kg. 2. Relevant equations How do I get the AMU? Or Atomic Mass Unit? 3. The attempt at a solution Ok, so I solved the answer in Kg. The answer in Kg is 8.999737e-28 Kg (This answer is correct). And I need to provide the answer in Atomic Mass Units also. I know the conversion factor is 1 amu = 1.6605e-27 Kg. My answer is .5419895815, but Webassign is not accepting the answer. Please help.
