Chapter 10, Problem 16QAP

(a)

Interpretation Introduction

Interpretation:

The molarity of the given ammonium 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 the diluted ammonia solution formed by diluting 300.0 mL of the commercial ammonia solution with water to make 2.5 L of the solution should be determined.

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

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