Precise measurements give the following masses: nuclide mass 239. 94 Pu 239.0522 u He 4.00260 u 242 96 Cm 242.0588 u He - particle 1 on 0 - le n 0 je Now consider the following nuclear reaction: 239. 94 Pu + 242 Cm + 96 Is energy released or absorbed by this reaction? 1.0086649 u -4 5.4858 10 u mass -4 5.4858 x 10 u If you said energy was released or absorbed, calculate how much energy is released or absorbed. Give your answer in both kJ/mol and MeV. Round each of your answers to 3 significant digits. Note: take particular care to keep enough digits in any intermediate calculation, and use enough digits in any scientific constants you need, since the data with which you are working are very precise. released absorbed neither released nor absorbed O I need more information to decide. kJ/mol Mev ☐ x10 X
