Chapter 9, Problem 8CR

Interpretation Introduction

Interpretation:

To determine the empirical formula of compound from the 0.7487 g of carbon.

Concept Introduction:

Percentage by mass of any element in the compound is the amount of that element in the total amount of the compound.

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

Number of moles can be calculated as follows;

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