Write the governing equation for the production of a stable daughter nuclide from a radioactive parent. b. Calculate the number of 137 Ba atoms formed after 15 years. c. Calculate the mass of 137 Ba atoms formed after 15 years. d. What letter represents the closest answer given in the question statement above?
