05657571&id=689555599&snapshotid=1550248& Q Search References Use the References to access important values if needed for this question. Iron-59 is a radioisotope that is used to evaluate bone marrow function. The half-life of iron-59 is 44.5 days. If you begin with 37.4 mg of this isotope, what mass remains after 117 days have passed? Since the decomposition is a radioactive decay reaction, it is first order. Submit Answer

Review | Constants Periodic Table In the parts that follow, use the following abbreviations for time If a substance is radioactive, this means that the nucleus is unstable and will therefore decay by any number of processes (alpha decay, beta decay, etc.). The decay of radioactive elements follows first-order kinetics. Therefore, the rate of decay can be described by the same integrated rate equations and half-life equations that are used to describe the rate of first-order chemical reactions: Measure of...
