Instructions to calculate molar mass (molecular weight) of a chemical compound:
- To calculate molar mass of a chemical compound enter it's formula and click 'Calculate!'
- In chemical formula you may use:
- Any chemical element
- Functional groups: Ph, Me, Et, Pr, Bu, Ac, For, Ts, Tos, Bz, TMS, tBu, Bzl, Bn
- parantesis () or brackets []
- Next values are numerically equivalent: molar mass, molecular mass, molar weight, molecular weight
Defentitions of molecular mass, molecular weight, molar mass and molar weight:
-
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.
