Chapter 9, Problem 6CR

Interpretation Introduction

Interpretation:

The term empirical and molecular formula for a substance should be determined. The information which is provided by both the formulas about a compound should be determined long with the information which must be known for a compound before the molecular formula can be determined. The reason that the molecular formula an integer multiple of the empirical formula should be determined.

Concept Introduction:

The chemical formula which represents the simplest whole number atoms ratio present in the compound is said to be empirical formula.

The chemical formula which shows the actual number of every atoms present in the compound is known as molecular formula.

Number of moles can be calculated as follows;

$\text{Nuumber of moles}\text{=}\frac{\text{mass in g}}{\text{molar}\text{mass}}$.
