If a star can convert all the He nuclei ...

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

(a) 7.6 MeV

B

(b) 56.12 MeV

C

(c) 10.24 MeV

D

(d) 23.4 MeV

Text Solution

Verified by Experts

The correct Answer is:
C
`4(`_2He^4)=`_8O^16`
Mass defect, `Deltam={4(4.0026)-15.9994}`
`=0.011` amu
`:.` Energy released per oxygen nuclei
`=(0.011)(931.48)MeV`
`=10.24` MeV
`:.` Correct answer is (c).
