The decay behavior of a radioactive substance obeys first order kinetics: In (N/N,) = -kt, where N is the amount of radioactive nuclei at time = t seconds, N, is the amount at O seconds, k is the first order rate constant, and t is the elapsed time. If the half-life of the radioactive nuclei is 10 minutes, calculate the amount that remains after 75 seconds. (Hint: at the first half-life, N = ½ N.) You should express your result as a percentage.
