The radioisotope phosphorus-32 is used in tracers for measuring phosphorus uptake by plants. The half-life of phosphorus-32 is 14.3 days. If you begin with 30.5 mg of this isotope, what mass remains after 27.5 days have passed? Since the decomposition is a radioactive decay reaction, it is first order.
