Chapter 25, Problem 29E

Interpretation Introduction

Interpretation:

The mass ratio in a meteorite needs to be determined.

Concept introduction:

A meteorite is found in outer space. It is a fragment of rock or iron.

The mass ratio of any object is found by dividing the two elements seen in the given substance. In this case, the given substance is the meteorite.

The time taken by any material to reduce to half its original volume is known as the half-life.

For a first order reaction, the relation between decay constant and half-life time will be as follows:

$k=\frac{0.6932}{t_{1/2}}$

Here, k is rate constant and $t_{1/2}$ is half time.
