Nuclear Conservation of Energy Worksheet
1.    Why isn't the sum of the masses of all nucleons in one nucleus equal to the mass of the actual nucleus? 
2. Calculate the binding energy in joules per nucleon of the nucleus of an atom of iron-56. The observed mass of one atom is 55.9349 amu. 
3. Calculate the binding energy in joules per nucleon of the nucleus of an atom of uranium-235. The observed mass of one atom is 234.98835 amu.  Calculate the amount of energy evolved from the fission of 1 mole of U-235. 
4. Calculate the binding energy in joules per nucleon of the nucleus of an atom of plutonium-244. The observed mass of one atom is 234.8991 amu. Calculate the amount of energy evolved from the fission of 1 mole of Pu-244.
5. Suppose that the total mass of reactants in a chemical reaction was 100.000000 g. How many kilojoules of energy would have to evolve from this reaction if the total mass of the products could be no greater than 99.99900 g?
