Chapter 4, Problem 4.18QP

(a)

Interpretation Introduction

Interpretation: The mass of the solute is to be calculated from the molarity and the volume of the solution.

Concept introduction: The number of moles of solute is calculated by the formula,

$\text{Number}\text{of}\text{moles}=\text{Molarity}\times \text{Volume}\text{of}\text{the}\text{solution}\text{in}\text{liter}$

The mass of the solute is calculated by the formula,

$\text{Mass}=\text{Number}\text{of}\text{moles}\times \text{Molar}\text{mass}$

To determine: The mass of the $\text{KBr}$ in the solution.

(b)

Interpretation Introduction

To determine: The mass of the ${\text{NaNO}}_3$ in the solution.

(c)

Interpretation Introduction

To determine: The mass of the ${\text{CH}}_{\text{3}}\text{OH}$ in the solution.
