In a typical nuclear fission reaction, it was found that there was a loss of mass of 0.2150 u. How much energy in MeV will be released from the reaction ? (`c=3xx10^8 ms^(-1)`)

Text Solution

Verified by Experts

Loss of mass, `Deltam=0.2150 u = 0.2150 xx (1.66xx10^(-27))` kg
Associated release of energy,
`DeltaE=Deltam.c^2 `
`=0.2150xx(1.66xx10^(-27)) xx (3xx10^8)^2`
`=3.2121xx10^(-11) J =(3.2121xx10^(-11))/(1.6xx10^(-19))` eV
`=200xx10^6` eV = 200 MeV
