a)

Mass of hydrogen m = 1.0 kg

Nuclear reaction: 4 ^{1}_{1} H \rightarrow ^{4}_{2} He

Energy released during the four hydrogen nuclei fuse to form a helium nucleus = 26 MeV

atomic mass of hydrogen = 4

Step 1:Number of atoms in the given mass of the substance

If 1g of hydrogen contains 6.023 * 10^{23} atoms

then, number of atoms in 1kg hydrogen = \frac{6.023 * 10^{23} * 1000}{4}

Step 2: Calculate the energy released in the nuclear fusion

The energy produced by the fusion of 1kg hydrogen

E = \text{number of atoms * energy/4nuclei } = \frac{6.023 * 10^{23} * 1000}{4} * 26 MeV

E = 39.149 * 10^{26} MeV

Energy released in 1kg hydrogen E_H = 39.149 * 10^{26} MeV

b)

Mass of Uranium [math] m = 1.0 kg [/math

The energy emitted by a single uranium nucleus fission is 200 MeV.

atomic mass of uranium 235 = 235

Step 1:Number of atoms in the given mass of the substance

If 1g of Uranium contains 6.023 * 10^{23}

then, number of atoms in 1kg Uranium = \frac{6.023 * 10^{23} * 1000}{235}

Step 2: Calculate the energy released in the nuclear fusion

The energy produced by the fusion of 1kg Uranium

E = \text{number of atoms * energy/nuclei } = \frac{6.023 * 10^{23} * 1000}{235} * 200 MeV

E = 5.106 * 10^{26} MeV

Energy released in 1kg uranium E_U = 5.106 * 10^{26} MeV

Comparison of energies released

E_H=39.149*10^{26} MeV and E_U = 5.106 * 10^{26} MeV

\frac{E_H}{E_U} = \frac{39.149 * 10^{26}}{5.106 * 10^{26}}

\frac{E_H}{E_U} =7.69 \approx 8

E_H = 8 * E_U

As a result, the energy produced in the fusion of one kilogram of hydrogen is approximately eight times that released in the fission of one kilogram of uranium.
