Ina nuclear fusion reactor two nuclei of deuterium merge, forming anucleus of helium. The mass of the deuterium nucleus, expressed inunits of atomic mass (u), is 2.0136u and of the helium nucleus isequal to 4.0015u (1u = 1.6605 × 10-27 kg). Determine the amount ofenergy released when 1.0 kg of deuterium is merged. Answer: 5,74 ×1014 J.
