I am specifically having difficulty in solving part d of this problem.    a) Calculate the number of grams of deuterium in a 54,300 L swimming pool, given deuterium is 0.0150% of natural hydrogen.   (b) Find the energy released in joules if this deuterium is fused via the reaction 2H + 2H → 3He + n.   (c) Could the neutrons be used to release more energy?   (d) Discuss the amount of this type of energy in a swimming pool as compared to that in, say, a gallon of gasoline, also taking into consideration that water is far more abundant. (Enter the ratio of the energy in the deuterium in the pool to the energy in a gallon of gasoline. The energy in a gallon of gasoline is 1.2 ✕ 108 J.) Edeuterium Egasoline  =
