$$Q=$$∑ $$Br-$$∑ $$BpC2Where$$ ∑ Br $$=$$ sum of the masses of reactantsand  ∑ $$Bp=sum$$ of the masses of the products∑ $$Br=2$$ x $$2.014741$$ amu∑ $$Bp=(3.016977)$$ amu∑ $$Bp=(3.016977+1.008987)$$ amu        $$=4.025964$$ amu∑ $$Br+$$∑ $$Bp=(4.029482-4.025964)$$ amu                          $$=0.003518$$ amuDecrease in mass appears as equivalent energy∴  Q $$=$$ $$0.003518$$ x $$931$$ MeV    $$=$$ $$3.27$$ MeV

In the nuclear reaction
${}_{1}H^{2} + {}_{1}H^{2} \to {}_{2}{He}^{3} + {}_{0}n^{1}$
If the mass of the deuterium atom = 2.014741 anu, mass of ${}_{2}{He}^{3}$ atom = 3.016977 amu and mass of neutron = 1.008987 amu, then the Q value of the reaction is nearly.
