Chapter 2, Problem 2.9MP

Interpretation Introduction

Interpretation:

The number of atoms of copper present in a copper rod of given length $9.85\text{cm}$ and radius of $1.05\text{cm}$ and density $8.96{\text{g/cm}}^{\text{3}}$ is to be calculated.

Concept introduction: The number of atoms in any sample of element is calculated by formula,
$\text{Number}\text{of}\text{atoms}=\text{Avogadro's}\text{number}\times \text{Number}\text{of}\text{moles}$

To determine: The number of atoms of copper present in a copper rod of length $9.85\text{cm}$ and a radius of $1.05\text{cm}$ and density $8.96{\text{g/cm}}^{\text{3}}$ .
