Chapter 3, Problem 3.14P

(a)

Interpretation Introduction

Interpretation:Total number of ions in $\text{38}{\text{.1 g SrF}}_2$ is to be calculated.

Concept introduction: The formula to convert moles to mass in grams is as follows:

  $\text{Mass}=\left(\text{Number of moles}\right)\left(\text{molar mass}\right)$

The formula to convert number of atoms to moles is as follows:

  $\text{Number of moles}=\frac{\text{Given number of molecules}}{6.022\times {10}^{23}}$

(b)

Interpretation Introduction
