Step 1:
I'll solve this problem step by step, following the specified LaTeX formatting guidelines:

Step 2:
: Understanding the Concept

The simplest formula of a compound (empirical formula) represents the simplest whole-number ratio of atoms in a chemical compound. This means reducing the subscripts to their lowest whole-number terms while maintaining the relative proportions of elements.

Step 3:
: Key Steps to Determine the Simplest Formula

To find the simplest formula, you typically follow these steps:

Step 4:

Determine the mass of each element in the compound

Step 5:

Convert masses to moles

Step 6:

Find the mole ratio

Step 7:

Divide by the smallest number of moles

Step 8:

Simplify to whole numbers if necessary

Step 9:
: Example Calculation Process

\text{Oxygen (O)}: 53.3\%
Let's illustrate with a general example: - Suppose you have a compound with:

Step 10:
: Mole Calculation

\frac{53.3}{16.00} = 3.33 \text{ moles of O}
- Assume 100g of compound - Convert percentages to grams - Divide by atomic masses

Step 11:
: Simplification

\frac{3.33}{3.33} : \frac{6.65}{3.33} : \frac{3.33}{3.33} = 1 : 2 : 1
- Divide each mole value by the smallest number (3.33)

Final Answer

The simplest formula (empirical formula) represents the lowest whole-number ratio of atoms in a chemical compound, obtained by reducing the mole ratios to their simplest terms.
