Calculate Q value of the following nuclear reaction `13^(Al^(27)) + 2^(He^(4)) rarr 14^(Si^(30)) + 1^(H^(1))`+ Q. The exact mass of `13^(Al^(27))` is 26.9815 amu, `14A^(Si^(30))` is 29.9738, `2^(He^(4))` is 4.0026 amu and `1^(H^(1))` is 1.0078 amu.

Text Solution

Verified by Experts

`triangle m`=(29.9738+1.0078)-(26.9815+4.0026)
=00.0025 amu
Q =0.0025 xx 931 MeV
=2.329 MeV
