Chapter 4, Problem 107E

Interpretation Introduction

Interpretation:

The atomic mass of iron is to be calculated with the help of table and listed atomic masses.

Concept Introduction:

The concept used to solve this problem is based on isotopes. Isotopes are the atoms having same number of protons but different neutrons.

Atomic mass is defined the average mass of the atom that formulate that element.

The average mass is also called the atomic mass.

Mass number is the sum of number of neurons and number of protons present in the atom.

Mass number is represented by A. Mathematically, mass number is calculated as:

$\text{A}=\text{number of neutrons}+\text{number of protons}$
