Calculate the energy generated in kilowatt hours, when \( 100 \mathrm{~g} \) of \( { }_{3} \mathrm{Li}^{7} \) are converted into \( { }_{2} \mathrm{He}^{4} \) by proton bombardment. Given : mass of \( { }_{3} \mathrm{Li}^{7} \) atom \( =7 \cdot 0183 \) a.m.u., mass of \( { }_{2} \mathrm{He}^{4} \) atom \( =4 \cdot 0040 \) a.m.u., mass of \( { }_{1} \mathrm{H}^{1} \) atom \( =1 \cdot 0081 \) a.m.u.
