Finding energy produced in nuclear fusion

  1. Jul 19, 2008 #1
    1. The problem statement, all variables and given/known data
    In a proposed fusion reactor, one possible reaction is H(2,1) + H(3,1) -> He(4,2) + n(1,0)

    How much energy might 150kg of the appropriate amount of isotopes of hydrogen produce?

    Values given
    Ar of H(2,1) = 2.014102
    Ar of H(3,1) = 3.016050
    Ar of He(4,2) = 4.002602
    Ar of n(1,0) = 1.008665

    2. Relevant equations
    E=mc^2?


    3. The attempt at a solution
    The correct answer is 5.07 x 10^16 J but I can't seem to get it. Any help is appreciated thanks.

    Start by figuring out the mass difference between the two sides of the reaction and multiply by c^2. Then figure out how many times you have to run that reaction to use up 150kg of H(2,1) + H(3,1).
