Calculate q value of the reaction, Chemistry

Problem:

Let us calculate Q value of the reaction 27Al (d, α) 25Mg

Answer:

Given that masses of

27Al = 26.981541        2H        = 2.014102

4He = 4.002603          25Mg    = 24.985839

Sum of masses of Reactants           = 26.981541 + 2.014102

= 28.995643 amu

Sum of masses of Products            = 24.985839 + 4.002603

= 28.988442 amu

...       Q = (28.995643 - 28.988442) × 931.5

= 6.701 MeV
