If a star can convert all the $He$ nuclei completely into oxygen nuclei, the energy released per oxygen nuclei is ( Mass of the nucleus is $4.0026$ $a m u$ and mass of oxygen nucleus is $15.9994$ $a m u$ )

Options:

Answer:

Solution:

$4 (_{2} H e^{4}) =_{8} O^{16}$

Mass defect,

$∆ m = {4 (4.0026) - 15.9994} a m u = 0.01 l a m u$

$∴$ Energy released per oxygen nuclei

$= (0.011) (931.48) M e V$

$= 10.24 M e V$
