Chapter 19, Problem 19.93SP

Interpretation Introduction

Interpretation:

With every half-life the concentration of the reactant decreases to half of the initial concentration.

Concept introduction:

$C$ is a radioactive isotope. All radioactive reactions are 1^st order reaction.

Given:

Age of the wooden object = 3000 years
Activity (Nuclear decay per minute per gram of carbon $C$ )=15.3

  $t_{1/2}=5715years$

To determine:

The $C$ activity in decays per events per minute of 1.0 g
