Chapter 20, Problem 48E

Interpretation Introduction

Interpretation: The mass of nuclide that remains in the patient at 5:00 p.m. the next day is to be determined.

Concept Introduction:

The half-life of the element is determined by the following formula:

$t_{1/2}=\frac{0.693}{k}$

The integrated rate law for the first-order reaction is given below.

$\text{ln}\frac{{\left[\text{A}\right]}_t}{{\left[\text{A}\right]}_{\text{0}}}\text{=}-kt$
