In fission,the percentage of mass converted into energy is about

Options

A. `94%`
B. `1%`
C. `0.1%`
D. `0.01%`

Answer

c

Explanation

Binding energy per nucleon of fission products is `8.5 MeV`.
Binding energy per nucleon of reactants`=7.6 MeV`
Increase in binding energy per nucleon is 8.5 -`7.6=0.9 MeV`
Energy released nucleon in fission is `0.9 MeV`.
Therefore, fractional energy relesed `=(0.9)/(931)=(1)/(1000)`
Percentage of mass converted into eenrgy durin g fission
`=(1)/(1000) xx 10=0.1%` .
