Homework Help: Fusion question. Answer, please!

  1. Apr 6, 2005 #1
    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 [itex] _{1}^{2}D [/itex] contains ~[itex] 6.023\cdot 10^{23} [/itex] 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.

    [tex] m_{_{1}^{2}D}\approx 2.0141018 \ \mbox{amu} [/tex]

    [tex] m_{_{2}^{4}He}\approx 4.0026033 \ \mbox{amu} [/tex]

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