Moles to Grams Calculator
Enter the number of moles and the molar mass in g/mol into the calculator to convert it into grams.
How to Convert Moles to Grams
Moles to Grams Formula
The following equation is used to convert moles into grams:
Grams = Moles × Molar Mass
Where:
Grams is the mass of the substance.
Moles is the amount of substance.
Molar Mass is the mass of one mole of a substance in grams per mole (g/mol).
To convert moles to grams, simply multiply the number of moles by the molar mass of the substance.
Mole Definition
A mole is a fundamental unit in chemistry that represents a specific quantity of particles, typically atoms or molecules. One mole is equivalent to 6.022 × 10²³ particles (Avogadro’s number). This unit allows chemists to easily scale up atomic-level measurements to macroscopic quantities.
Gram Definition
A gram is a metric unit of mass used widely in scientific and everyday measurements. In chemistry, grams are used to express the mass of a compound or element based on its molar mass.
Moles to Grams Examples
Example 1:
Convert 2 moles of water (H₂O) to grams
Molar mass of H₂O = 18.015 g/mol
2 × 18.015 = 36.03 grams
Example 2:
Convert 0.5 moles of sodium chloride (NaCl) to grams
Molar mass of NaCl = 58.44 g/mol
0.5 × 58.44 = 29.22 grams
Example 3: Convert 3 moles of carbon dioxide (CO₂) to grams
Molar mass of CO₂ = 44.01 g/mol
3 × 44.01 = 132.03 grams

FAQs
- Are moles and grams the same?
No. Moles measure the amount of substance; grams measure mass. - Why do we need molar mass?
Molar mass acts as a bridge between the number of particles (moles) and mass (grams). - What units are used in this conversion?
Moles (mol) and grams (g), with molar mass expressed in g/mol. - Where is this conversion used?
In chemistry labs, pharmaceuticals, chemical manufacturing, and academic research. - What is molar mass based on?
It’s derived from the atomic or molecular weight listed on the periodic table. - Can this calculator convert in reverse (grams to moles)?
Yes. Use the formula: Moles = Grams ÷ Molar Mass - What if I don’t know the molar mass?
You can calculate it by adding the atomic masses of all atoms in the molecule.
