It is estimated that the atomic bomb exploded at Hiroshima released a total energy of `7.6xx10^(13)J`. If on the average, 200MeV energy was released per fission, calculate (i) the number of Uranium atoms fissioned, (ii) the mass of Uranium used in the bomb.
Text Solution
Verified by Experts
Number of Uranium atoms fissioned `n=("total energy released")/("energy released" //"fission")` `=(7.6xx10^(13))/(200xx1.6xx10^(-13))` `=2.375xx10^(24)` `"Mass of Uranium" = ("Mass number")/("Avogadro's number") xx n` `(235xx2.375xx10^(24))/(6.023xx10^(23))=926.66g`
