Chapter 10, Problem 10.83E

Interpretation Introduction

Interpretation:

The amount of sample, of a $100$-milligram radioactive element, that remained after eight days is to be predicted.

Concept introduction:

The time required for the concentration of the reactant to reduce to half of its initial concentration gives the half-life of the reaction. The half-life of the reaction depends on the initial concentration of the reactant except for the first order reaction.
