Hard

A nuclear power plant uses Uranium-235 as fuel. In a nuclear fission reaction, one atom of U-235 releases approximately 200 MeV of energy. If 1 kg of U-235 undergoes complete fission, and given that 1 eV = 1.6 × 10^-19 J, the number of atoms in 1 kg of U-235 is approximately 2.56 × 10^24, then the total energy released would be closest to:
