Chapter 12, Problem 12.116AP

(a)

Interpretation Introduction

Interpretation: The diameter and the length of the nonorod of gold is given. The approximate number of atoms of gold present in each nanorod; the number of unit cells corresponding to each nanorod and the mass of each nanorod is to be calculated.

Concept introduction: The volume of the cylinder is calculated by the formula,

$\text{Volume}=\frac{\text{π}\times {\left(\text{Diameter}\right)}^2\times \text{Height}}{4}$

The volume of the sphere is calculated by the formula,

$\text{Volume}=\frac{\text{4π}\times {\left(\text{Radius}\right)}^3}{3}$

To determine: The approximate number of atoms of gold present in each nanorod.

(b)

Interpretation Introduction

To determine: The number of unit cell of gold corresponding to each nanorod.

(c)

Interpretation Introduction

To determine: The mass of each nanorod.
