An example of the neutron absorption reaction is .
1 0 n+10 5 B-->7 3 Li+ 4 2 He

The rest masses of each particle in atomic mass units (u) are
1 0 n= 1 u
10 5 B=10 u
7 3 Li =7 u
4 2 He= 4 u

where 1u=1.66x10^-27 kg.

calculate Q
Q= in MeV
I have the same question please someone help me solve this. Thank you

    ¹₀n+¹º₅B = ⁷₃Li+⁴₂He

    Δm = m(¹₀n) + m(¹º₅B) – m(⁷₃Li)-m(⁴₂He)=
    =1.009 + 10.811 – 6.941 – 4.003 = 0.876 u.

    ΔE=mc²=0.876 •1.66•10⁻²⁷•9•10¹⁶ =
    =1.31•10⁻¹º J= =8.18•10⁸ eV =818 MeV

    Hi Elena thank you so much for your help but this answer is wrong i don't know why. Maybe because c is squared and did you squared c ? Please help me out
