Answer
The amount of energy that is released is $5.58~MeV$ which is $8.93\times 10^{-13}~J$
Work Step by Step
We can find the mass $M$ that is lost:
$221.97039~u = 217.96289~u+4.00151~u+M$
$M = 221.97039~u - 217.96289~u - 4.00151~u$
$M = 0.00599~u$
$M = (0.00599~u)(\frac{931.494~MeV/c^2}{1~u})$
$M = 5.58~MeV$
We can assume that the missing mass is converted into energy. We can find this energy:
$E = Mc^2$
$E = (5.58~MeV/c^2)(c^2)$
$E = 5.58~MeV$
$E = (5.58~MeV)(\frac{1.60\times 10^{-13}~J}{1~MeV})$
$E = 8.93\times 10^{-13}~J$
The amount of energy that is released is $5.58~MeV$ which is $8.93\times 10^{-13}~J$.
