Suppose $56$Fe$($nuclear mass $55\mathrm{.}85$ u$)$ splits into two $28$Si nuclei $($nuclear mass $28\mathrm{.}09$ u$).$ Is energy added to make this process occur or is energy released by this process?$$ How much?$$ Recall that $1$ amu $==931\mathrm{.}4942$MeV.

Group of answer choices

$153$ MeV is released

$307$ MeV must be added

$153$ MeV must be added

$26,000$ MeV is released

$307$ MeV is released
