Molybdenum-99 decays to technetium-99. Technetium-99 is also radioactive but has a long half life of 6 hours. It decays by emitting gamma rays and this is useful for imaging. rate = - d[A] = k [A]2 dt Suppose you perform an imagining experiment on a patient which takes 2 hours. How much of the technetium-99 will have decayed in 2 hours?
