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. A mole of N2 is approximately 28 g, and Avogadro’s number is approximately 6.022 x 1023, so about 4.65 x 10-23 g or 4.65 x 10-26 kg. Molar mass calculator computes molar mass, molecular weight and elemental composition of any given compound. 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. Its molecular formula is written as NHO 3 and its molar mass is 63. The molar mass of nitrogen (N) is approximately 14.01 grams per mole of nitrogen atoms. This Calculator has been tested on Internet Explorer version 6 only,įirefox might not show all fields correctly. Air is a mixture of several gases, where the two most dominant components in dry air are 21 vol oxygen and 78 vol nitrogen. Nitrogen has a steric number of 3, while the oxygen atom in the OH ion has a steric. For question or remarks please contact us. !!! Lenntech BV cannot be held responsible for errors in the calculation, Make sure you enter the molecule of crystallization at last (e.g. 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. Definition and molecular weight (molar mass) of some common substances.

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. 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 ).
