### Computing molar mass (molar weight)

To calculate molar mass of a chemical compound enter its formula and also click "Compute". In chemical formula you might use:Any chemical aspect. Capitalize the first letter in chemical symbol and usage reduced instance for the staying 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, Dmgparantesis () or brackets <>.Common compound names.Instances of molar mass computations: NaCl, Ca(OH)2, K4,CuSO4*5H2O,water,nitric acid,potassium permanganate,ethanol,fructose.Molar mass calculator additionally displays widespread compound name, Hill formula, elemental complace, mass percent composition, atomic percent compositions and also permits to transform 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.Instances of molecular weight computations: C<14>O<16>2, S<34>O<16>2.

### Definitions of molecular mass, molecular weight, molar mass and also molar weight

Molecular mass (molecular weight) is the mass of one molecule of a substance and also is expressed in the linked 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.Weights of atoms and isotopes are from NIST short article.Give us feedago about your suffer through Molecular Weight Calculator.Related: Molecular weights of amino acidsmolecular weights calculated today
