Interpretation Introduction

Interpretation:

The number of moles present in $1.42\times {10}^{24}$ atoms of aluminium is to be calculated.

Concept introduction: The number of moles in any sample of element is calculated by formula,

$\text{Number}\text{of}\text{moles}=\frac{\text{Number}\text{of}\text{atoms}}{\text{Avogadro's}\text{number}}$

To determine: The number of moles present in $1.42\times {10}^{24}$ atoms of aluminium.
