Molar Mass/Molecular Weight Calculator

Formula





(% by Element, mass, # Atoms, mass)











Molar Mass Calculator to find the Molecular Weight.

You can type in molecular formula like CH3CH2COOH or K2Cr2O7 or KFe[Fe(CN)6]3

For example, when you type in NaCl, then the result Molar Mass = 58.44, % of Na = 39.33949349760438, % of Cl = 60.6656399726215, 1.000 g of NaCl = 17.1116mmole, 1 mmole of NaCl = 0.058g.
