A small atomic bomb releases energy equivalent to the detonation of 20,000 tons of TNT; a ton of TNT releases 4x10^9 J of energy when exploded. Using 2x10^13 J/mol as the energy released by fission of 235U, approximately what mass of 235U undergoes fission in this atomic bomb? Explain in detail how you arrived at the answer.
