Question
Chapter 21, Problem 37E
Interpretation Introduction
Interpretation: The time that is necessary to replace the cobalt-60 is to be stated when the original sample was purchased in June 2013.
Concept introduction: For a radioactive substance, the half-life is a characteristic constant that measures the time required for a given substance to reduce half of its atom in the reaction as a consequence of decay. The half-life depends upon the substance involved in a reaction.
To determine: The time that is necessary to replace the cobalt-60 when the original sample was purchased in June 2013.

A 1000 ppm Zn solution was prepared by dissolving the necessary amount of solid Zn(NO3)2 in water. The standards can be prepared by diluting the 1000 ppm Zn solution. Table 1 shows one possible set of serial dilutions (stepwise dilution of a solution) that Reagan could perform to make the necessary standards. Solution A was prepared by diluting 5.00 ml of the 1000 ppm Zn standard to 50.00 ml. Solutions C-E are called "calibration standards" because they will be used to calibrate the atomic absorption spectrometer. a.
