(choose chapter or problem)

(III) The americium nucleus, \({ }_{95}^{241} \mathrm{Am}\), decays to a neptunium nucleus, \({ }_{93}^{237} \mathrm{~Np}\), by emitting an alpha particle of mass 4.00260 u and kinetic energy 5.5 MeV.. Estimate the mass of the neptunium nucleus, ignoring its recoil, given that the americium mass is 241.05682 u.
