Interpretation Introduction

Interpretation: The information needed to calculate the number of atoms of 1cm3 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=MassVolume

Equation for finding Volume of cube is,

Volume=a3,asideofcube

Conversion formula for mass of a molecule and number moles,

Numberofmoles=MassingramsMolarmass

Equation for number of atoms is,

Number of moles×6.022×1023atoms=number of atoms

### Explanation of Solution

Reason for correct option:

The value of volume of iron is given, so the mass of iron can be calculated by using the equation of density from volume and mass.

Hence,

Option (d) the density of iron is required.

The number of moles of atom can be calculated from mass of atom and molar mass,

Numberofmoles=MassingramsMolarmass

Hence,

Option (b) the molar mass of iron is required.

Equation for number of atoms is,

Number of moles×6.022×1023atoms=number of atoms

Hence,

Option (c) Avogadro’s number is required.

The outline of procedure for the calculation of number of atoms is,

1cm3×density(g/cm3)×1molmolarmass(g)×6
