Chapter 3, Problem 3.124MP

Interpretation Introduction

(a)

Interpretation:

An empirical formula of compound needs to be determined.

Concept introduction:

The simplest positive integer ratio of atoms of the chemical compound is called as empirical formula. From the empirical formula, the actual number of atoms present in the compound cannot be determined.

Interpretation Introduction

(b)

Interpretation:

The molecular formula of compound needs to be determined.

Concept introduction:

Chemical symbol used for constituent elements which are followed by the subscript describing the present numerals of atoms of each element in the molecule is the molecular formula.

The value of empirical and molecular formula may be the same or molecular formula may be a multiple of compound’s empirical formula.
