Find the binding energy per nucleon of a

^{7}\text{Li}

nucleus. Data: • Atomic mass of

^{7}\text{Li}

atom

m(^{7}\text{Li}) = 7.016003\,\text{u}

• Proton mass

m_p = 1.007276\,\text{u}

• Neutron mass

m_n = 1.008665\,\text{u}

• Electron mass

m_e = 0.0005486\,\text{u}

•

1\,\text{u} = 931.5\,\text{MeV}

Give your answer in MeV per nucleon (to two significant figures).
