The figure below shows the change in the number of nuclei of a radionuclide in a sample with time as Ln (N) versus t. Use the data depicted in the figure to determine: (a) the initial number of nuclei in the sample, (b) the initial activity of the radionuclide, (c) the decay constant of the radionuclide, (d) the half-life time of the radionuclide, (e) the mean time of the radionuclide, (f) the activity of the radionuclide after 1 hr. 11 10 100 200 300 400 500 Time (minutes) 7.
