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.)

When a star has exhausted its hydrogen fuel, it may fuse other nuclear fuels. At temperatures above 1.0 x 10° K, helium fusion can occur. Write the equation for the following processes.
(a) Two alpha particles fuse to produce a nucleus A and a gamma ray. What is nucleus A? (Enter the mass number in the first raised box, the atomic number in the second lower box, and the
element, with charge if necessary, in the third box.)
(b) Nucleus A absorbs an alpha particle to produce a nucleus "B" and a gamma ray. What is nucleus B? (Enter your answer using the same format as above.)
(c) Find the total energy (Q) released in the reactions given in parts (a) and (b). Note: the mass of 4
