 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.
