Calculate the energy released when three alpha particles combine to form a `^12 C` nucleus. The atomic mass of `_2^4 He` is `4.002603 u`.

Text Solution

Verified by Experts

The mass of a `.^(12)C` atom is exactly 1`2 u`. The energy released in the reaction is `3(_2^4He)rarr._6^(12)C)`
`[3m(._(2)^(4)He) -m(._(6)^(12)C) ]c^(2)=[3xx4.002603 u-12u](931 MeV//u)`
`=7.27 MeV` .
