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

Options:

Answer:

Solution:

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

Mass defect, $Δ m = 4 (4.0026) - 15.9994 = 0.011 amu$

Therefore Energy released per oxygen nuclei

$= (0.011) (931 . 48) MeV$

$= 10.24 MeV$

Therefore the Correct answer is ( $10.24 MeV$ ).
