Chapter 8, Problem 56E

Interpretation Introduction

Interpretation:

The mass of the isotope left after 92 day for the given mass and half-life of isotope, is to be determined.

Concept Introduction:

The time needed for a quantity to minimize it to half its initial amount is known as half-life. It can be represented as ${\text{t}}_{\text{1/2}}$.

The elements which consist of the same atomic number and different mass number are known as isotopes.
