Chapter 19, Problem 19.105CP

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:

Activity (Nuclear decay per minute per gram of carbon $C$ )=15.3
Nuclear decay in the bone= 2.9 radioactive per minute per gram of carbon

$t_{1/2}=5715years$

To determine:

To determine the age BP of a bone fragment.
