find the amount of energy produced in jaoules due to fission of 1 g of `""._(92)U^(235)` assuming that 0.1% of mass is transormed into enengy ,Atomic mass of `""._(92)U^(235)=235 ` amu , Avogodro number `N_(A)=6.023xx10^(23).` Given that the energy released per fission is 200 MeV.

Explanation

it is given that 0.1 % of 1gm of `""_(92) U^(235)` is being used so ,
mass used ,`m=(0.1)/(100)xx1=00^(-3) g`
Number of fissions `=("given mass ")/("Atomic mass ")xxN_(a)=(10^(-3))/(235)xx6.023xx10^(23)`
Energy produced ,E=Number of fissions `xx` Energy relased per fission
`=(6.023xx10^(20))/(235)xx200xx1.6xx10^(-13)=8.2xx10^(7)J`
`( :' Me V = 1.6xx10^(-13) J)`
