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.)

I asked this question once and the answer returned was correct, but I couldn't follow the work so I'm hoping you can write it more clearly:
A proposed nuclear reactor facility will have an electrical power output of 805 MW with a 30.2% efficiency in converting nuclear to electrical power. Assuming the average fission reaction produces 227 MeV, how many reactions will take place at the facility every second?
