Calculate the energy release for the complete fusion of one mole of deuterium

H + H = He + energy

i can't do the signs for mass number etc. it quotes the Avogadro constant so that's a clue but help!!!

1 mole of $_{1}^{2}D$ contains ~$6.023\cdot 10^{23}$ atoms....

When fusing 2 atoms how much energy is released...?

yeah i did all that but i got bogged down in finding the mass change. remind how to find the mass of atoms when you have the atomic no. + Av. constant please.

$$m_{_{1}^{2}D}\approx 2.0141018 \ \mbox{amu}$$

$$m_{_{2}^{4}He}\approx 4.0026033 \ \mbox{amu}$$

That's all u need to know,u have the reaction's equation,already.
