Chapter 21, Problem 54E

The mass of a hydrogen atom $\left({}_1^1\text{H}\right)$ is 1.007825 arm; that of a tritium atom $\left({}_1^3\text{H}\right)$ is 3.01605 amu; and that of an a particle is 4.00150 amu. How much energy in kilojoules per mole of ${}_2^4\text{He}$ produced is released by the following fusion reaction: ${}_1^1\text{H}{+}_1^3\text{H}{\to }_2^4\text{He}$
