A Grams to Mole Calculator is a chemistry tool that converts the mass of a substance in grams (g) into the number of moles (mol) using the substance's molar mass. This conversion is fundamental in chemistry and is widely used in laboratory experiments, stoichiometry, solution preparation, chemical reactions, and academic studies.
Because every chemical substance has a unique molar mass, converting grams to moles requires knowing the molar mass of the compound or element. Our Grams to Mole Calculator performs this calculation instantly, eliminating the need for manual computation and reducing the chance of errors.
Whether you're a student, teacher, researcher, or laboratory professional, this calculator provides a fast and reliable way to determine the amount of substance in moles.

How to Use the Grams to Mole Calculator
Using the calculator is quick and easy.
Step 1
Enter the mass of the substance in grams (g).
Step 2
Enter the molar mass of the substance in grams per mole (g/mol).
Step 3
Click the Calculate button.
The calculator instantly displays the number of moles (mol).
Required Inputs
The calculator requires only two essential values:
- Mass (grams)
- Molar mass (g/mol)
These inputs are sufficient to perform the conversion.
Calculator Output
After calculation, users receive:
- Number of moles (mol)
- Mass entered (g)
- Molar mass used (g/mol)
Formula Used
The calculator uses the standard chemistry equation:
Moles (mol) = Mass (g) ÷ Molar Mass (g/mol)
Where:
- Mass is the quantity of the substance in grams.
- Molar Mass is the mass of one mole of the substance.
- Moles represent the amount of the substance.
Example Calculation
Suppose you have:
- Mass = 90 g
- Molar Mass = 18 g/mol (water)
Calculation:
Moles = 90 ÷ 18
= 5 mol
Result:
90 grams of water equals 5 moles.
Another Example
Suppose:
- Mass = 88 g
- Molar Mass = 44 g/mol (carbon dioxide)
Calculation:
88 ÷ 44
= 2 mol
Result:
88 grams of carbon dioxide equals 2 moles.
Understanding the Mole
A mole is the standard SI unit for measuring the amount of a substance.
One mole contains:
6.022 × 10²³ particles
These particles can be:
- Atoms
- Molecules
- Ions
- Formula units
This number is known as Avogadro's Number and forms the basis of many chemical calculations.
What Is Molar Mass?
Molar mass is the mass of one mole of a substance.
It is expressed in:
grams per mole (g/mol)
Examples include:
| Substance | Molar Mass |
|---|---|
| Water (H₂O) | 18.015 g/mol |
| Carbon Dioxide (CO₂) | 44.01 g/mol |
| Oxygen (O₂) | 32.00 g/mol |
| Nitrogen (N₂) | 28.02 g/mol |
| Sodium Chloride (NaCl) | 58.44 g/mol |
