Calculate the total binding energy of an

^{4}\text{He}

nucleus. Given: • Atomic mass of

^{4}\text{He}

atom

m(^{4}\text{He}) = 4.002603\,\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}

Express your answer in MeV (to two significant figures).
