Transcription: Here's the uranium-234 decay that you've seen before. Here are the mass values in units of MeV over C squared and the total mass on each side of this equation is exactly the same. And here are the corresponding energy values in units of MeV. Because of E equals MC squared, the numbers are the same. It's just the units which are different and that makes it very easy to work out the energy released. Here in the fourth line are the mass assesses. Notice that they give exactly the same number for the energy released as using the full mass, so they're just as good for finding if the decay process o ...
