Grams To Moles Formula

Grams to Moles Formula

Understanding Grams To Moles Formula is very important while studying Chemistry. Studying the basic concepts well will help students to understand the more complex topics in a thorough manner.


This article discusses the Grams To Moles Formula. A gram is a metric system unit of mass equal to 0.001 kilograms. Grams To Moles Formula is a very popular and widely used unit of measurement. 1 gram is about the size of a pen cap or a small paper clip.

In the International System of Units, a mole is a measurement unit for the amount of substance. It has a value of 6.02214076 times 1023 constitutive particles. Also, the Avogadro number is 6.02214076 multiplied by 1023. Furthermore, this number was chosen to make one mole’s mass of a chemical compound, in the Grams To Moles Formula, equal to one molecule’s average mass of the compound, in Dalton. As a result, one mole of water contains 6.02214076 times 1023 molecules and weighs approximately 18.015 grams. One water molecule has an average mass of 18.015 Dalton.

Derivation of Grams to Moles Formula

Many chemical equations require the amount of a substance to be expressed in moles. In addition, converting grams of a substance to moles is a common conversion:

Moles/molar mass = grams

It is more commonly written in chemical conversion as

1 gram = 1 mole/ grams = moles

1 mole = 1 gram of molar mass

Grams and Moles in Chemistry

Uses of Grams To Moles Formula:

Small Scales that are available in the kitchen, use Grams To Moles Formula. This scale is used to measure the amount of meat, flour, and sugar. Furthermore, by using a kitchen scale, one can obtain the amount of the substance in pounds, ounces, or grams. A laboratory, like a kitchen, has a requirement to count the number of substances. Chemists also use a device known as an analytical balance. This device measures the concentration of a chemical substance or compound. Above all, this measurement is usually done in grams.

Moles are the standard unit of measurement in chemistry. Furthermore, this unit expresses the quantity of a chemical compound. One thing to keep in mind is that there is no direct way to measure moles. The reason for this is that when using an analytical balance, one can only physically measure the amount of a compound in grams.

However, there is a bright side. The number of moles can be converted from the number of grams of a compound.

When converting the Grams To Moles Formula, two factors must be considered:

  1. The number of grams of a compound and 
  2. The molecular weight of the compound.
