Use this periodic table for calculating molar mass for any chemical formula. Please note that the chemical formula is not limited to the known chemical compounds.
Select elements to see the molar mass of the compound. By clicking the compound you see a detail page of the elements showing mass fraction percentages. There you can also edit the amounts of elements.
Works with iPhone and iPad.
Atomic weights are according to IUPAC © 2013 (Pure Appl. Chem., Vol. 85, pp. 1047-1078, 2013). Revised values are taken from IUPAC website. Conventional atomic weights are used for boron, bromine, carbon, chlorine, hydrogen, lithium, magnesium, nitrogen, oxygen, silicon, sulfur and thallium. For radioactive elements with no stable isotopes, mass number of the most stable isotope is used.
