Interpretation Introduction

Interpretation: The mass of phosphorus-32 left from an original sample of 175 mg Na332Po4after 35.0 days needs to be determined.

Concept Introduction:The probability of decay per unit time of radioactive nuclei is called Decay constant. The decay constant is related to the half-life of the nuclide T 1/2 by the following relation:

   T 1/2 = ln 2/λ
