A G to Mol Calculator is a chemistry tool used to convert the mass of a substance in grams (g) into the amount of substance in moles (mol) using its molar mass. This calculation is one of the most common in chemistry and is essential for laboratory work, chemical equations, stoichiometry, solution preparation, and educational purposes.
Since different substances have different molar masses, the same mass in grams can represent different numbers of moles. By entering the mass of the substance and its molar mass, this calculator instantly determines the number of moles.
Our G to Mol Calculator provides fast, accurate, and easy mole conversions for students, teachers, researchers, and chemistry professionals.

How to Use the G to Mol Calculator
Using the calculator is very simple.
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 inputs:
- Mass (grams)
- Molar mass (g/mol)
These values are sufficient to calculate the number of moles.
Calculator Output
After calculation, users receive:
- Number of moles (mol)
- Mass entered
- Molar mass used
Formula Used
The calculator uses the standard chemistry formula:
Moles (mol) = Mass (g) ÷ Molar Mass (g/mol)
Where:
- Mass is measured in grams.
- Molar Mass is measured in grams per mole.
- The result is expressed in moles.
Example Calculation
Suppose you have:
- Mass = 36 grams
- Molar Mass = 18 g/mol (water)
Calculation:
Moles = 36 ÷ 18
Moles = 2 mol
Result:
36 grams of water equals 2 moles.
Another Example
Suppose:
- Mass = 58.5 g
- Molar Mass = 58.5 g/mol (sodium chloride)
Calculation:
58.5 ÷ 58.5
= 1 mole
Result:
58.5 grams of sodium chloride equals 1 mole.
What Is a Mole?
A mole is the SI unit used to measure the amount of a substance.
One mole contains approximately:
6.022 × 10²³ particles
These particles may be:
- Atoms
- Molecules
- Ions
- Formula units
This value is known as Avogadro's Number.
What Is Molar Mass?
Molar mass is the mass of one mole of a substance.
It is expressed as:
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 |
| Sodium Chloride (NaCl) | 58.44 g/mol |
| Glucose (C₆H₁₂O₆) | 180.16 g/mol |
