Suppose two $56$Fe$($nuclear mass $55\mathrm{.}85$ u$)$ nuclei are combined to form $112$Cd $($nuclear mass $112\mathrm{.}4$ u$).$ Is energy added to make this process occur or is energy released by this process?$$ How much?$$ Recall that $1$ amu $=$ u$=931\mathrm{.}494$c$2$MeV.

Group of answer choices

$326$ MeV must be added

$652$ MeV must be added

$53000$ MeV is released

$652$ MeV is released

$326$ MeV is released
