Solution

Mass defect is the amount by which the mass of an atomic nucleus differs from the sum of the masses of its constituent particles, being the mass equivalent of the energy released in the formation of the nucleus.
Nuclear binding energy per nucleon for the given atom= $\frac{B E}{A}$
$= \frac{127.5 M e V}{16}$
$= 7.96 M e V$
Value of $1 e V$ is equal to $1.6 \times 10^{- 19} J$ .
