No doubt a little negligence in the lab may let the chemical reaction to become uncontrolled. This is why it is very necessary to analyse the reaction kinematics appropriately to avoid any hurdle.

When carrying out a chemical reaction, it is very important to keep a record of the simplest whole number ratio of the chemical substances in the chemical reaction. To better do this, you may better use the online empirical formula calculator.

This tool is especially indeed to calculate what is the smallest ratio of atoms that could react in a chemical reaction. And this ratio is known as the empirical formula that is the topic of today’s discussion as well.

**What Is the Empirical Formula?**

**It is the smallest number of atoms that could be taken as reactive components of the compounds in a chemical reaction.**

**How To Calculate Empirical Formula?**

The best method considered so far is the use of the combustion analysis calculator. But we will be taking you through the manual steps as well!

**Calculate the Number of Grams**

This is the first step in determining the smallest ratio formula of any substance. Whenever you are given a certain percentage of a substance, you must convert it to the relative amount of grams. This can instantly be done with the online empirical formula calculator by calculator-online.net.

**Calculate the Number of Moles**

The very next step is to calculate the number of moles present in the grams you determined.

The formula for this is as follows

**Moles = Given Mass/Atomic Mass**

The empirical formula calculator also utilises the same expression for instant mole computation without compromising accuracy. This may seem a little bit tricky to a few people. This is why we better suggest you ask yourself at every step whether you are getting grip on the concept or not.

**Division By Atomic Mass**

Whether or not there is no chance of any decimal or fractional value, you must at least practice it. Let yourself divide grams by moles or moles by grams to know the methodology behind converting decimals to whole numbers.

Let us take an example! What would you learn if you divide 20 grams by 34moles of the substance? Definitely, you will get an idea of calculating the atomic mass which is the key parameter to determine the empirical expression.

This practice of calculations will assist you to get a firm grip on computations in a round off manner.

**Division By Smallest Number**

This is the second last step in which you will get decimal, fractional, and whole numbers that represents the quantity of the atoms involved in the chemical reaction.

Now what you need to do here go by dividing all the numbers by the smallest one. If the answers are whole numbers, let them be as it is.

But if they are not, a round-off to the nearest whole number to define the quantity. The empirical formula calculator no doubt does the same in seconds, thereby reducing your waste of time on computations.

**Last Words**

So we are pretty sure you are now an expert at calculating the empirical formula of any compound or substance. If you feel any hurdle in the process, do not worry and let the empirical formula calculator do the calculations for you to get the desired outputs.
