Chapter 3, Problem 3.94AP

a.

Summary Introduction

To determine:

The molar mass of ${\text{NaC}}_{\text{2}}{\text{H}}_{\text{3}}{\text{O}}_{\text{2}}$.

Concept introduction:

The molar mass is defined as the number, which is equal to the sum of the atomic masses of the atoms in a molecule. The molecular mass gives the mass of molecule relative to that of the ${\text{C}}^{12}$ atom, which is taken to have a mass of $12$.

b.

Summary Introduction

To determine:

The molar mass of ${\text{KMnO}}_{\text{4}}$.

Concept introduction:

The molar mass is defined as the number, which is equal to the sum of the atomic masses of the atoms in a molecule. The molecular mass gives the mass of molecule relative to that of the ${\text{C}}^{12}$ atom, which is taken to have a mass of $12$.

c.

Summary Introduction

To determine:

The molar mass of ${\text{C}}_2{\text{HBrClF}}_{\text{3}}$.

Concept introduction:

The molar mass is defined as the number, which is equal to the sum of the atomic masses of the atoms in a molecule. The molecular mass gives the mass of molecule relative to that of the ${\text{C}}^{12}$ atom, which is taken to have a mass of $12$.
