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.)

(b) Find the mass remaining after three weeks.
(c) How long will it take for the sample to decay to a mass of 30 g? (Round t to the nearest day.)
An accident at a nuclear power plant has left the surrounding area polluted with radioactive material that decays naturally. The initial amount of radioactive material present is 42 su (safe units), and 5 months later it is still 31 su.
a.) write a formula giving the amount A(t) of radioactive material (in su) remaining after t months.
(Use integers or decimals for any numbers in the expression. Round to three decimal places needed.)
b.) what amount of radioactive material will remain after 11 months?
c.) how long will it be until A = 1 su, so it is safe for people to return to the area?
