Chapter 9.6, Problem 9.9P

(a)

Interpretation Introduction

Interpretation:

Amount of solute or solvent needed to prepare the following solution is to be identified.

Concept Introduction:

In order to express the concentration, many units have been used. One among them is

$\text{Mass/volume}\text{percent}\text{concentration(m/v)\%}$ , defined as number of grams of solute dissolved in $\text{100mL}$ of solution.

$\text{(m/v)\% =}\frac{\text{Mass of solute(g)}}{Volume\text{of}\text{solution(mL)}}\text{×100}$

(b)

Interpretation Introduction

Interpretation:

Use of $\text{500mL}$ volumetric flask to prepare $\text{7}\text{.5\%}$ solution of acetic acid is to be identified.

Concept Introduction:

In order to express the concentration, many units have been used. One among them is

$\text{Mass/volume}\text{percent}\text{concentration(m/v)\%}$ , defined as number of grams of solute dissolved in $\text{100mL}$ of solution.

$\text{(m/v)\% =}\frac{\text{Mass of solute(g)}}{Volume\text{of}\text{solution(mL)}}\text{×100}$
