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)

A

`7.6 MeV`

B

`56.12 MeV`

C

`10.24 MeV`

D

`23.4 MeV`

Text Solution

Verified by Experts

The correct Answer is:
C
`4(._(2)He^(4))=._(8)O^(16)`
Mass defect
`Deltam={4(4.0026)-15.9994}=0.011 am u`
`:.` Energy released per oxygen nuclei
`=(0.011)(931.48) MeV=10.24 MeV`
