Computing molar mass (molar weight)To calculate molar mass of a chemical compound enter its formula and click 'Compute'. In chemical formula you may use:
Examples of molar mass computations:
- Any chemical element. Capitalize the first letter in chemical symbol and use lower case for the remaining letters: Ca, Fe, Mg, Mn, S, O, H, C, N, Na, K, Cl, Al.
- Functional groups: D, Ph, Me, Et, Bu, AcAc, For, Ts, Tos, Bz, TMS, tBu, Bzl, Bn, Dmg
- parantesis () or brackets .
- Common compound names.
Molar mass calculator also displays common compound name, Hill formula, elemental composition, mass percent composition, atomic percent compositions and allows to convert from weight to number of moles and vice versa.
Computing molecular weight (molecular mass)
To calculate molecular weight of a chemical compound enter it's formula, specify its isotope mass number after each element in square brackets.
Examples of molecular weight computations:
Definitions of molecular mass, molecular weight, molar mass and molar weight
Weights of atoms and isotopes are from NIST article.
- Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
- Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
