SUMMARY
The fission of one uranium-235 nucleus releases approximately 4.73×10-11 joules of energy. This calculation involves applying Einstein's mass-energy equivalence formula, E=mc2, where the mass difference is determined by combining the masses of the fission products. The discussion emphasizes the importance of significant figures and proper unit representation in scientific calculations.
PREREQUISITES- Understanding of nuclear fission processes

What are "them"?mccarthyp64 said:1. How much energy is released during the
fission of one uranium-235 nucleus?
2. e=mc2 lol
3. I thought of putting them together but then how to separate them?
If you start using six significant figures, it is silly to have more than six in your answer. And since you are adding two quantities of different orders of magnitude, you should have even fewer. Your answer also needs to have units.
Solve the problem by doing exactly what the problem says to do: find the mass difference, then find the energy.
