Chapter 8, Problem 115QRT

(a)

Interpretation Introduction

Interpretation:

Molar mass of the compound has to be determined.

Concept Introduction:

Density can be calculated by the equation given below:

  $\text{Density = }\frac{\text{Mass}}{\text{Volume}}$

(b)

Interpretation Introduction

Interpretation:

Empirical formula and molecular formula for the compound has to be given.

Concept Introduction:

Empirical Formula:

Empirical formula of a compound is the simplest formula which provides the lowest positive whole number ratio of atoms that exists in the compound. The molecular formula of a compound can either be same as the empirical formula or a multiple of it.

Percent composition:

Percent composition is nothing but providing the mass percent of each element present in the compound.

(c)

Interpretation Introduction

Interpretation:

Lewis structure of each of the isomer of compound has to be determined.

Concept-Introduction:

Lewis structure

Electron dot structure also known as Lewis dot structure represents the number of valence electrons of an atom or constituent atoms bonded in a molecule.  Each dot corresponds to one electron.
