Question

how much energy is released when 2 mole of U235 is fissioned?

Answer 1

Fission produces about 200mev per nucleus .
Two mole of nuclei is thus 2.4e26mev or3.9e13joule or 10kilotons

Answer 2

Answer:

For Uranium-235 atom 200MeV of energy is released per fission (from one nucleus).

Energy released by fission of 2 moles

= 2 x Na x 200

= 2 x 6.02 x 10²³ x 200

= 400 x 6.02 x 10²³

$= 24 \times {10}^{25} MeV$
