Problem

The mass of the

^{7}_{3}\!\text{Li}

nucleus is

1.1655\times10^{-26}\,\text{kg}

. The masses of a free proton and a free neutron are

m_p = 1.67262\times10^{-27}\,\text{kg}

and

m_n = 1.67493\times10^{-27}\,\text{kg}

, respectively. Calculate the binding energy of the

^{7}_{3}\!\text{Li}

nucleus in joules. (Take

c = 3.00\times10^{8}\,\text{m s}^{-1}
