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.)

Hello please someone help me answer this problem set, thank you!
Part A:
A particular smoke detector contains 1.05 μCi of 241Am241Am, with a half-life of 458 years. The isotope is encased in a thin aluminum container. Calculate the mass of 241 Am in grams in the detector.
Express your answer numerically in grams.
Part B:
Fears of radiation exposure from normal use of such detectors are largely unfounded. Identify reasons why 241 Am smoke detectors are perfectly safe.
Select all that apply
a. The penetrating power of αα radiation is limited.
b. Ions get trapped by electrodes.
c. The amount of americium is very little.
d. The number of αα particles leaving the case is low.
e. The detector has a plastic cover.
f. The detector is housed in an aluminum case.
Show the complete solution. Kindly, include the necessary table of values.
1. Initially, there is 50 mg of a certain radioactive material present and after 2 hours, it is observed that the material has lost 10 % of its original mass. Find:
a. the mass of the material after 4 hours
b. the time at which the mass has decayed to one–half of its initial mass (half–life of the material)

This first question that is answered. The mass difference between two isotopes is sometimes just a neutron mass. The spectrometer should separate them very well. For such an isotope combination, the difference in radius should be around 1 cm. That is r2 - r1 = 1 cm. In order to achieve this, choose a magnetic field with a magnitude in Tesla (maximum magnetic field you can obtain from a conventional magnet is around 2.5 T so be far away from this value) and choose the direction also. Then determine the velocity of isotope you need. Last calculate radius r of a Pb204 ^(-) smallest isotope.
