Chapter 10, Problem 13QAP

(a)

Interpretation Introduction

Interpretation:

The number of moles of aluminum sulfate before dilution of given solution needs to be calculated.

Concept Introduction :

The molarity is defined as the ratio of number of moles of solute to the volume of solution in liters.

The formula for molarity is:

  $\text{Molarity =}\frac{\text{number of moles of solute}}{\text{volume of solution in liter}}$

(b)

Interpretation Introduction

Interpretation:

The molarity of aluminum sulfate, aluminum ions, and sulfate ions in the diluted solution should be calculated.

Concept Introduction :

The mole is a degree or the base unit for the quantity of substance exists in the given sample. One mole is number that is equivalent to $6.022\times {10}^{23}$ particles, also recognized as the Avogadro's number.
