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

10.24 MeV

B

0

C

7.56 MeV

D

5 MeV

Text Solution

Verified by Experts

The correct Answer is:
A
Four He Fused to produce one oxygen.
`4 ""_(2)He^(4) rarr ""_(8)O^(16)`
Mass defect `= 4 m_(He) - m_(o)`
`Delta m = 4 xx 4.0026 - 15.9994 = 0.011` a.m.u
Equivalent energy, `E = Delta mc^(2)`
`rArr" "E = 0.011 xx 931 = 10.24` MeV
