Answer:
B. Nuclear fission
Explanation:
Nuclear binding energy is used to determine whether fission or fusion will be a favorable process. The mass defect of a nucleus represents the mass of the energy binding the nucleus, and is the difference between the mass of a nucleus and the sum of the masses of the nucleons of which it is composed.
Assuming total mass to be 100 g
Mass of C = 52.93 g
=> Moles of C = 
Mass of H = 5.92 g
=> Moles of H=
Mass of N = 41.15 g
=>Moles of N=
Simplest mole ratio of the atoms in the compound:

Empirical formula mass=
Multiple n = 
Molecular formula= 
<span>Avogadro's number
represents the number of units in one mole of any substance. This has the value
of 6.022 x 10^23 units / mole. This number can be used to convert the number of
atoms or molecules into number of moles.
4 mol He ( </span>6.022 x 10^23 atoms / mole ) = 2.4088 x 10^34 atoms He
Al2(CrO4)3 = 401.9 grams per mole
