1 calculate the total binding energy and the binding energy per nucleo

Question

1. Calculate the total binding energy and the binding energy per nucleon of (a) 7Be and (b) 56Fe. An isotope of fission is 1515m, with a half-life of 90 y. How long will it take 0.05 g to decay
to 0.01 g? 5. Assume that a source of 60Co can be safely managed if it contains less than 0.01 Ci. How long
would it take for a source containing 5 Ci of 60Co to reach this value?
6. Write the following in equation form to show the balance of atomic and mass number and the
compound nucleus: (a) 'Li(p, a), (b) Be(d, p), (c) 'Be(p, a), and (d) ºBe(d, a). 9. 10 mCi of 90Sr is separated from a fission product mixture and allowed to sit for 90y to grow in.
What is the activity of 90Y at (a) 20 h and (b) 600 h?
