Chapter 19, Problem 19.95SP
Interpretation Introduction

Interpretation:

The decay equation can therefore be written:

Nt=Noeλt

Concept introduction:

Since A1840r was also formed from K1940

  K19400=K1940t+A1840rt

Where  A1840rt is the number of A1840r atoms formed after time t.
The decay equation can therefore be written:

  Nt=Noeλt

Given:

K1940A1840r+e10

Half-life of K1940 = 1.25×109 years
K1940 decays to give A1840r

Concentration of K1940 in the rock = 3.35mmol

Concentration of A1840r in the rock = 0.25mmol

To determine:

The time taken by the rock to cool
