$$\left(\begin{matrix}2 \ 1\end{matrix}\right) H + \left(\begin{matrix}2 \ 1\end{matrix}\right) H --> \left(\begin{matrix}4 \ 2\end{matrix}\right)He $$

so i think you're supposed to find the mass defect (the difference between them and use $E=mc^2$

@arronq I understand I use that equation, but how would i set it up
