What is the IUPAC name of C6H5N

Calculation of the molar mass (molar weight)

To calculate the molar mass of a chemical compound, enter its formula and click Calculate "." For the chemical formula you can use:
  • Any chemical element. Starting with an uppercase letter in the chemical symbol and lowercase letters in the remaining digits: 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
  • round brackets () and square brackets [].
  • Common names of substances.
Calculation examples of the molar mass: NaCl, Ca (OH) 2, K4 [Fe (CN) 6], CuSO4 * 5H2O, water, nitric acid, potassium permanganate, ethanol, fructose.

The molar mass calculator also shows normal substance names, Hill equations, elemental composition, percentage mass composition, percentage atomic composition and can convert weights into the corresponding number of moles and vice versa.

Calculation of the molecular weight (molecular mass)

To calculate the molar mass of a chemical compound, put its formula and the isotope mass number after each element in square brackets.
Examples of calculation of molecular weight: C [14] O [16] 2, S [34] O [16] 2.

Definition of molecular mass, molecular weight, molar mass and molar weight

  • The Molecular mass (Molecular weight) is the mass of a molecule of a substance and is given in atomic mass units (u) (1 u = 1/12 of the mass of a carbon-12 atom).
  • The Molar mass (Molar weight) is the mass of one mole of a substance and is given in g / mol.
Weights of atoms and isotopes are taken from NIST article.
