Chapter 14, Problem 20PE

(a)

Interpretation Introduction

Interpretation:

Moles of solute in $0.75\text{ L}$ of $1.50M{\text{ HNO}}_3$ have to be determined.

Concept Introduction:

Molarity is amount of solute per $1\text{ L}$ of solution. Formula for molarity is as follows:

  $\text{Molarity of solution}=\frac{\text{Moles of solute}}{\text{Volume }\left(\text{L}\right)\text{ of solution}}$

(b)

Interpretation Introduction

Interpretation:

Moles of solute in $\text{10}\text{.0 mL}$ of $\text{0}\text{.75 }M{\text{ NaClO}}_3$ have to be determined.

Concept Introduction:

Refer to part (a).

(c)

Interpretation Introduction

Interpretation:

Moles of solute in $\text{175 mL}$ of $\text{0}\text{.50 }M\text{ LiBr}$ have to be determined.

Concept Introduction:

Refer to part (a).
