Chapter 2, Problem 2.7P

Interpretation Introduction

(a)

Interpretation:

The number of iron atoms in one ton of iron should be determined.

Concept Introduction:

Formula to calculate a number of iron atoms is:

  $\text{N=}\frac{\text{mass×Avogadro constant}}{\text{atomic mass of iron}}$

Interpretation Introduction

(b)

Interpretation:

The volume occupied by one mole of boron in cubic centimeters needs to be determined.

Concept Introduction:

The volume occupied by one mole of boron is given by:

  $V=\frac{\text{Atomic}\text{mass}\text{of}\text{boron}}{\text{Density}}$
