Chapter 12, Problem 12.115AP

(a)

Interpretation Introduction

Interpretation: The unit cells present in a cubic silver particle with an edge length of $25\text{nm}$ and number of silver atoms in that particle is to be calculated. The number of particles present in $1360\text{μg}$ of silver per sock is to be stated.

Concept introduction: Silver crystallizes in a fcc crystal arrangement. This crystal structure has 8 atoms at each corner of the cube and 6 atoms at each face of the cube.

To determine: The number of unit cells are present in a cubic silver particle with an edge length of $25\text{nm}$.

(b)

Interpretation Introduction

To determine: The number of silver atoms is there in a cubic silver particle.

(c)

Interpretation Introduction

To determine: The number of particles does $1360\text{μg}$ of silver per sock corresponds to.
