![]() a pollution of 1 gram of benzene in a certain amount of water converts to N A/78.11≈ 7. Using the above calculator you could find that e.g. Or 1 mole of a substance will contain Avogadro's number of that substance. The term " mole" is defined in that one mole of a substance with a molecular (or atomic) mass of one (1), will have a mass of 1 gram. It is defined to be 1/12 of the mass of one atom of carbon-12 and in older works is also abbreviated as "amu".Īlso, important in this field is Avogadro's number (N A) or Avogadro's constant (6.0221 x 10 23). In related terms, another unit of mass often used is Dalton (Da) or unified atomic mass unit (u) when describing atomic masses and molecular masses. Molecular mass or molar mass are used in stoichiometry calculations in chemistry. This Calculator has been tested on Internet Explorer version 6 only,įirefox might not show all fields correctly. For question or remarks please contact us. !!! Lenntech BV cannot be held responsible for errors in the calculation, (a) molecular CO2, empirical CO2 (b) molecular C2H2, empirical CH. Make sure you enter the molecule of crystallization at last (e.g. A molecular formula is a representation of a molecule that uses chemical symbols to. The calculator handles at most two different bracket levels. The molecular mass calculator will recognize the entered formula's, which are included in the list of organic compounds. ![]() Or you can choose by one of the next two option-lists, which contains a series of common organic compounds (including their chemical formula) and all the elements. Compounds of nitrogen and oxygen: NO2 - nitrogen dioxide N2. This online calculator you can use for computing the average molecular weight (MW) of molecules by entering the chemical formulas (for example C3H4OH(COOH)3 ). CO - carbon monoxide (notice that it is not mono-oxide, but monoxide) CO2 - carbon dioxide. Molecular Weight Calculator Molecular Weight Calculator
