## What is Empirical Formula?

The empirical formula for a compound provides the most straightforward ratio of the number of various atoms that are present. The sulfur and oxygen molecules, sulfur monoxide, and disulfuric dioxide have the same empirical formula. They have the same molecular formulas, which indicate how many atoms are present in each molecule of a chemical compound.

## Examples of Empirical Formula

Example 1:

Calculate the mole and mole ratio if the mass of carbon = 121, Hydrogen = 141, and Oxygen = 181

Solution:

 Element C H O Mass 121 g 141 g 181 g Mole 121/12 141/1.008 181/16.01 Mole 10.08 139.88 11.31 Divide by small 10.08/10.08 139.88/10.08 11.31/10.08 Mole Ratio 1 14 2

Example 2:

Calculate the mole and mole ratio if the mass of carbon = 32, Hydrogen = 24, and Oxygen = 54

 Element C H O Mass 32 g 24 g 54 g Mole 32 /12 24 /1.008 54 /16.01 Mole 2.67 23.81 3.37 Divide by small 2.67 / 2.67 23.81 / 2.67 3.37 / 2.67 Mole Ratio 1 9 2
