Energy from Fusion

Calculate the following:

The mass difference.

The energy released per fusion.

Slide 46

Energy from Fusion

The total mass before fusion (LHS of the equation):

The total mass after fission (RHS of the equation):

3.345 x 10-27 + 5.008 x 10-27 = 8.353 x 10-27 kg

6.647 x 10-27 + 1.675 x 10-27 = 8.322 x 10-27 kg

Slide 47

Energy from Fusion

m = total mass before fission – total mass after fission

m = 8.353 x 10-27 – 8.322 x 10-27

m = 3.1 x 10-29 kg

Slide 48

Energy from Fusion

E = mc2

m = 3.1 x 10-29 kg

c = 3 x 108 ms-1

E = E

E = 3.1 x 10-29 x (3 x 108)2

E = 2.79 x 10-12 J

The energy released per fusion is 2.79 x 10-12 J.
