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)

`7.6MeV`

`56.12MeV`

`10.24MeV`

`23.9MeV`

Text Solution

Verified by Experts

The correct Answer is:

When four helium nuclei are fused together, one oxygen nucleus is formed. The reaction is
`4xx2He^(4)to._(8)O^(16)+Q`
Mass defect, `Deltam=4xxm_(He)-m_(O_(2))`
`=4xx4.0026-15.9994=0.011a.m.u.`
Energy released
`E=0.011xx931=10.24MeV`
