Answer

See explanation.

Work Step by Step

The mass defect is the total mass of the constituent particles, minus the atom’s mass. a. $146m_n+92m_H-m_U=1.93u$. b. The binding energy is $(1.93u)\frac{931.5 MeV}{u}=1.80\times10^3MeV$. c. Binding energy per nucleon: divide the exact binding energy by 238 nucleons to obtain 7.55 MeV/nucleon. This answer agrees with the book's diagram.
