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

Options

A. `0.01%`
B. `10%`
C. `1%`
D. `0.1%`

Answer

D

Explanation

Consider the fussion reaction suggested by Hahn and Strassman.
`""_(92)U^(235)+""_(0)n^(1)to""_(56)Ba^(141)+""_(36)Kr^(92)+3""_(0)n^(1)`.
For the reaction,
Initial masses `{:(""_(92)U^(235)-235.0439a.m.u),(underline(""_(0)n^(1)-1.0087a.m.u)),("Total="236.0526a.m.u):}`
Final masses `{:(""_(56)Ba^(141)-140.9139a.m.u),(""_(36)Kr^(92)-91.8973a.m.u),(underline(3""_(0)n^(1)-3.0261a.m.u)),("Total="235.8373a.m.u):}`
`therefore` Percentage of mass converted into energy
`=(236.0526-235.8373)/(236.0526)=0.0912%cong0.1%`
