Chapter 14, Problem 28PE

(a)

Interpretation Introduction

Interpretation:

Molarity of solution prepared by mixture of $175\text{ mL}$ of $3.0M{\text{ H}}_2{\text{SO}}_4$ with $275\text{ mL}$ of ${\text{H}}_2\text{O}$ has to be determined.

Concept Introduction:

Expression for molarity equation is as follows:

  $M_1{V}_1=M_2{V}_2$        (1)

Here,

$M_1$ is molarity of original solution.

$V_1$ is volume of original solution.

$M_2$ is molarity of final solution.

$V_2$ is volume of final solution.

(b)

Interpretation Introduction

Interpretation:

Molarity of solution prepared by mixture of $350\text{ mL}$ of $\text{0}\text{.10 }M{\text{ CuSO}}_4$ with $150\text{ mL}$ of ${\text{H}}_2\text{O}$ has to be determined.

Concept Introduction:

Refer to part (a).

(c)

Interpretation Introduction

Interpretation:

Molarity of solution prepared by mixture of $50.0\text{ mL}$ of $\text{0}\text{.250 }M\text{ HCl}$ with $\text{25}\text{.0 mL}$ of $\text{0}\text{.500 }M\text{ HCl}$ has to be determined.

Concept Introduction:

Different concentration terms are employed to describe concentration of solution. Below mentioned are some concentration terms.

1. Molarity

2. Molality

3. Mass percent

4. Volume percent
