- A reaction takes place with a mass defect of 0.030kg. How much energy does this correspond to? (I don't need answered)
- How much mass defect is required to release 5.5 x 1020 J of energy? (I don't need answered)
22. A reaction of 2.5kg of fissionable material takes place. Assuming a 0.10% mass defect, how much energy is released? This is the group of questions that question 22 is grouped in. There is no other information I can offer. It isn't related to any other question.

How much energy is lost or gained when Co-60 undergoes between decay? Mass of Co-60 is 59.9338 amu, Mass of Ni-60 is 59.9308 amu. Look at the following reaction 238 92U 234 90Th + 42He What would be the energy released for the nuclear reaction above 238 92U = 238.0003 amu, 23490Th = 233.9942 amu and 42He = 4.0015 amu. What would be energy release if 1 Kg of 238U disintegrate to become 234 90Th + 42He. 1 amu=931.5 MeV,...

Question 7a: On Earth in 2017, the amount of electrical energy used was 8.03 x 1016 J. How much mass would need to be converted directly to energy to release this much energy? Question 7b: Imagine this conversion of mass to energy all came from nuclear fission reactions of the element uranium. Assume the reaction is 35% efficient: that means that the mass you calculated above to produce the electrical energy is only 35% of the total mass...
