Definition of Moles
A mole (symbol: mol) is a fundamental unit of measurement in chemistry that is used for calculating the quantity of a substance. It offers a method for quantifying the number of particles (atoms, molecules, ions, etc.) in a given sample by comparing the number of particles to the mass of the substance.
A mole is the specific quantity of a substance that contains precisely 6.02214076 × 10²³ fundamental entities, including atoms, molecules, ions, and electrons. This number is referred to as Avogadro's number (NA).
For example:mole of carbon atoms contains 6.022 × 1023 carbon atoms.
How to Calculate Moles from Grams?
To convert grams to moles, you need to use the molar mass of the substance. The molar mass is the mass of one mole of a substance, usually expressed in grams per mole (g/mol). Each element has a unique molar mass, which is listed on the periodic table. To calculate moles from grams, use the following formula:
Mass, molar mass, and the number of entities (atoms, molecules, etc.), in a substance provide the formula for calculating moles from grams. The molar mass acts as a link between the macroscopic (grams) and microscopic (moles) levels, allowing scientists to determine how much of a substance is present in a chemical reaction or process. To find out the amount of moles present, divide the substance's mass in grams by its molar mass.
For example:Mass of NaCl = 50 grams, Molar Mass of NaCl = 58.44 g/mol Moles of NaCl = 50 g/58.44 g/mol = 0.855 moles of NaCl| Substance | Molar Mass (g/mol) | Mass (grams) | Moles (mol) |
|---|---|---|---|
Water (H₂O) | 18.015 | 18.015 | 1 |
Sodium Chloride (NaCl) | 58.44 | 58.44 | 1 |
Carbon Dioxide (CO₂) | 44.01 | 44.01 | 1 |
Oxygen (O₂) | 32.00 | 32.00 | 1 |
Nitrogen (N₂) | 28.014 | 28.014 | 1 |
Glucose (C₆H₁₂O₆) | 180.16 | 180.16 | 1 |
Hydrochloric Acid (HCl) | 36.46 | 36.46 | 1 |
Ammonia (NH₃) | 17.03 | 17.03 | 1 |
Sulfuric Acid (H₂SO₄) | 98.08 | 98.08 | 1 |
Methane (CH₄) | 16.04 | 16.04 | 1 |

How to Use a Grams to Moles Calculator
This process is simplified by our calculator, which allows you to enter the mass in grams as well as the molar mass of the substance. Here is a step-by-step guide for using the calculator:
Type in the amount of the substance in grams. For example, if you have 50 grams of sodium chloride (NaCl), type '50' into the mass field.
In the next step enter the molar mass of the substance. For example, for sodium chloride, the molar mass is 58.44 g/mol.
Enter the mass and molar mass, then click the 'Calculate' button. It will give you the number of moles of the substance by dividing the mass by the molar mass.
