Answer :

Final answer:

The fission of 1 kg of U-235 produces an energy equivalent to about 14,000 barrels of crude oil or 600,000 gallons of gasoline, which is approximately 2.5 million times more energy than burning 1 kg of coal.

Explanation:

The energy generated by the fission of 1 kg of U-235 is substantial. To work out the total energy, we must first calculate the number of U-235 atoms in 1.00 kg. This involves converting the mass of uranium-235 to moles, using Avogadro's number. For 1.00 kg of U-235, this will be approximately 4.25 moles, or 2.56 × 10²⁴ atoms.

With each fission of U-235 producing about 1.8 × 10¹⁰ kJ per mole, meaning the fission of 1 kg of U-235 produces an energy equivalent to about 14,000 barrels of crude oil or 600,000 gallons of gasoline. That's approximately 2.5 million times more energy than burning 1 kg of coal. Despite this, fission fuel, such as U-235, is scarce, and less than 1% of naturally occurring uranium is readily usable for nuclear fission.
