How does the mass per nucleon in uranium compare with the mass per nucleon in its fission fragments?

(a) For the nuclei N and o, determine the difference in binding energy per nucleon (in MeV). (Let the mass of a proton be 14 1.0078 u, the mass of a neutron be 1.0087 u, the mass of N be 14.0031 u, and the mass of O be 14.0086 u.) MeV (b) This difference in binding energy is due to which of the following? 14 Greater proton attraction for the 0 nucleus 14 Greater neutron attraction for the O nucleus 14 Greater electron attraction for the 0 atom Greater proton repulsion for the o nucleus O Greater electron repulsion for the O 14 O atom 14 O Greater neutron repulsion for the o nucleus

Is the mass of an atomic nucleus greater or less than the sum of the masses of the nucleons composing it? Why don’t the nucleon masses add up to the total nuclear mass?

A large power reactor that has been in operation for some months is turned off, but residual activity in the core still produces 150 MW of power.  If the average energy per decay of the fission products is 0.96 MeV, what is the core activity in units of curies?
