Finding energy produced in nuclear fusion

[SpikeOut]

Homework Statement

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

Homework Equations

E=mc^2?

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).
