8. [5 pt] In stars like the Sun, helium nuclei are formed by fusing hydrogen nuclei together in a process
known as the proton-proton chain. One step of the proton-proton chain consists of a deuterium nucleus
($$m_d = 2.01410 u$$) fusing together with a hydrogen nucleus ($$m_H = 1.00783 u$$) to form a helium-3 nucleus
($$m_{He} = 3.01603 u), where $$u = 1.6605 × 10^{−27}$$ kg. How much energy is released during this fusion reaction?
