2) Suppose that we have 100 cm' of water (p = 1g.cm"), which is D;0 in a proportion of 0.015% (D stands for deuterium, or H). a) Compute the energy (in J) that would obtain from this sample if all the deuterium were to be consumed in the reaction H + H- 'H +p, which is known to release an energy output of 4.0 MeV. b) As an alternative, compute the energy (in J) that would be released if two-thirds of the deuterium were fused (according to the previous reaction) to form 'H, which then combines with the remaining one third according to the reaction H+ 'H → *He +n, known to release an energy output of 17.6 MeV. c) Which of the processes a) or b) produces more energy? Given: N= 6.022x10" mot P. ->
