The activity of a sample of a radioisotope at some time is 10.3 mCi and 0.36 h later it is 6.70 mci. Determine the following. (a) Decay constant (in s-1) 0.33e-3 s-1 (b) Half-life (inh) x How is the half-life related to the decay constant? h 02857 (c) Nuctel in the sample when the activity was 10.3 mCI 1.15e18 x How is the number of nuclei related to the decay constant and the activity? nuclei (d) Activity (in mCi) of the sample 2.50 h after the time when it was 10.3 mci 167.7 How is the activity of a radioactive sample at any time related to the activity at some time t = 0, the decay constant and time? mci
