![]() 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. Ionic charges are not yet supported and will be ignored. Use uppercase for the first character in the element and lowercase for the second character. For question or remarks please contact us. To balance a chemical equation, enter an equation of a chemical reaction and press the Balance button. Since there is an equal number of each element in the reactants and products of H2O2 + SO2 H2SO4, the equation is balanced. Count the number of atoms of each element on each side of the equation and verify that all elements and electrons (if there are charges/ions) are balanced. !!! Lenntech BV cannot be held responsible for errors in the calculation, Step 4: Substitute Coefficients and Verify Result. Step 4: Substitute Coefficients and Verify Result. Make sure you enter the molecule of crystallization at last (e.g. The calculator handles at most two different bracket levels. Strontium Chloride + Sulfuric Acid Hydrogen Chloride + Celestine. 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. 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 ).
