Problem: The nuclear reaction that powers a radioisotope thermoelectric generator is  94 238Pu  →   92 234U + 2 4He. The atomic masses of plutonium-238 and uranium-234 are 238.049554 amu and 234.040946 amu, respectively. The mass of an alpha particle is 4.001506 amu. How much energy in kJis released when 1.00 g of plutonium-238 decays to uranium-234?

🤓 Based on our data, we think this question is relevant for Professor Davis' class at UCF.
