Atoms And Nuclei Question 349
Question: If a star can convert all the He nuclei completely into oxygen nuclei, the energy released per oxygen nuclei is [Mass of $ He $ nucleus is 4.0026 amu and mass of Oxygen nucleus is 15.9994 mu]
Options:
A) 7.6 MeV
B) 56.12 MeV
C) 10.24 MeV
D) 23.9 MeV
Show Answer
Answer:
Correct Answer: C
Solution:
-
$ 4_{2}^{4}He\xrightarrow{}_{8}^{16}O $
$ B.E.=\Delta m\times 931.5MeV $
$ =(4\times 4.0026-15.9994)\times 931.5=10.24MeV $
