Question

The first atomic bombs each released about 8 1013 J of energy, the same energy that would have been released in the explosion of 20,000 tons of TNT. What mass of fissioning U-235 is required to release this much energy? (The bombs contained considerably more fissionable nuclei than the nuclei that actually fissioned.)

Step 1

To do this, we need to know the energy released per mole of TNT and the molar mass of TNT. The molar mass of TNT (trinitrotoluene) is approximately 227.13 g/mol. The energy released per mole of TNT is 4184 J/g * 227.13 g/mol = 9.5 x 10^5 J/mol. Therefore, the Show more…
