Chapter 2, Problem 165SCQ

Interpretation Introduction

Interpretation: The information needed to calculate the number of atoms of $1c{m}^3$ iron from the given options is to be identified and the procedure for this calculation has to be outlined.

Concept introduction:

Equation for density from volume and mass is,

  $Density=\frac{Mass}{Volume}$

Equation for finding Volume of cube is,

  $Volume=a^3,a-sideofcube$

Conversion formula for mass of a molecule and number moles,

$Numberofmoles=\frac{Massingrams}{Molarmass}$

Equation for number of atoms is,

    $\text{Number of moles}\times \text{6}\text{.022}\text{×}{\text{10}}^{\text{23}}\text{atoms}\text{=}\text{number of atoms}$
