STEP-BY STEP SOLUTION PLEASE

Iodine-135 is a radioactive isotope, with mass 134.9100503 u.

a.determine how much energy is emitted in a single decay of iodine -135 and find recoil energy of the daughter nucleus, following decay.

b if a sample has 5.000 x 10^6 Iodine-135 nuclei, what is the activity of the sample and how long will it take the sample to decay to 1% of its initial value?
