Frequently Asked Questions
Molar mass is the mass of one mole of a substance, expressed in grams per mole (g/mol). It numerically equals the substance's atomic or molecular weight.
One mole contains Avogadro's number of particles: 6.022 × 10²³. This is true for atoms, molecules, ions, or any chemical entity.
Sum the atomic masses of all atoms in the molecular formula. For H₂O: (2 × 1.008) + (1 × 16.00) = 18.016 g/mol.

About This Calculator
Calculate the molar mass (M) of a chemical compound from sample mass and number of moles (M = m/n).
How to Use the Molar Mass Calculator
- 1Enter the sample mass (m) in grams — the measured weight of your chemical sample.
- 2Enter the amount of substance (n) in moles.
- 3The calculator computes molar mass: M = m / n in grams per mole (g/mol).
- 4You can also rearrange: m = M × n (to find mass) or n = m / M (to find moles).
Molar Mass Formula (M = m/n) Explained
Molar mass (M) connects the microscopic world of atoms to measurable laboratory quantities. The formula M = m / n gives the mass per mole, where m is the sample mass in grams and n is the number of moles. This value equals the sum of atomic weights from the periodic table for one formula unit of the substance.
Molar mass is crucial for converting between mass and moles in stoichiometric calculations. For example, knowing that NaCl has M = 58.44 g/mol tells you that 58.44 grams of salt contains exactly one mole (6.022 × 10²³ formula units) of NaCl. This bridges the gap between what you weigh on a balance and what participates in chemical reactions.
Worked Molar Mass Examples
Example 1: Finding Molar Mass from Lab Data
- A lab sample weighs 180.16 g and contains 1.0 mol of substance.
- M = m / n = 180.16 / 1.0 = 180.16 g/mol.
- This matches glucose (C₆H₁₂O₆): (6×12.01) + (12×1.008) + (6×16.00) = 180.16.
The substance is glucose (C₆H₁₂O₆) with a molar mass of 180.16 g/mol.
Example 2: Converting Grams to Moles
- You have 100 g of calcium carbonate (CaCO₃). Its molar mass is 100.09 g/mol.
- Moles: n = m / M = 100 / 100.09 ≈ 0.999 mol.
- This is very close to 1 mole — CaCO₃ conveniently has a molar mass near 100.
100 grams of CaCO₃ is approximately 1.0 mole, containing 6.022 × 10²³ formula units.
Frequently Asked Questions About Molar Mass
What is the difference between molar mass and molecular weight?
They are numerically identical but conceptually different. Molecular weight (relative molecular mass) is dimensionless, while molar mass has units of g/mol. Both are calculated the same way from atomic masses.
Does molar mass change with isotopes?
Yes. Different isotopes have different atomic masses. The standard molar mass uses the weighted average atomic mass from the periodic table, which accounts for natural isotope abundances.
Why is the mole concept important in chemistry?
Chemical reactions occur between individual atoms and molecules. The mole lets us scale from the atomic level to laboratory quantities. Balanced equations tell us the mole ratios of reactants and products, enabling precise measurements.
