Calculate the energy released by the fission `1 g` of `.^(235)U` in joule, given that the energy released per fission is `200 MeV`.
(Avogadro's number `=6.023xx10^(23))`

Text Solution

Verified by Experts

The number of atoms in 1 g of ` "" ^(235) U`
`= ("Avogadro.s number" )/("Mass number")=`
`(6. 023 xx 10 ^(23))/(235) = 2. 563 xx 10 ^(21)`
Energy released per fission `= 200 MeV`
` = 200 xx 10 ^(6) xx 1.6 xx 10 ^(-19) = 3.2 xx 10 ^(-11) J.`
Energy released by 1 g of `"" ^(235) U`
= Number of atoms `xx` energy released per fission
`= 2. 563 xx 10 ^(21) xx 3.2 xx 10 ^(-11) J = 8. 202 xx 10 ^(10) J`
