Consider the nuclear reaction
92U238 --> 90Th234 + 2He4
The nuclei in this reaction have the masses
238.0003 amu for 92U238, 233.9942 amu for 90Th234 and 4.0015 amu for 2He4.
(a) Find ΔE when one mole of 92U238 nuclei undergoes this reaction
(b) Use the answer to (a) to find ΔE when one 92U238 nucleus undergoes this reaction.
