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. The Molecular Weight Calculator can calculate molecular weights for simple chemical formulas involving stable elements and their. 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. The question looks like this: given this. The most common type of stoichiometry calculation is a mass-mass problem. For question or remarks please contact us. The atomic mass calculator takes the number of protons and neutrons in an atom and displays the atomic mass in atomic mass units and kilograms. If you want to know the number of grams needed of each substance, you can multiply by the molar mass of each substance: NaOH 2.10 mol 39.997 g/mol 83.9937g Mg (OH)2 1.05 mol 58.319 g/mol 61.23495g NaCl 2.10 mol 58.442 g/mol 122. a quantitative study of chemical changes. !!! 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. Mass relative formula mass × amount 44 × 0.25 11 g Example 2 Calculate the mass of 0.10 mol of iron. 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. He can do this because the magnitude of an element's relative atomic mass on the periodic table is defined to be. Calculate the maximum mass of water that can be made from an excess of carbon dioxide and 95.6 g of lithium hydroxide. 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 ). Sal begins with the element's relative atomic masses (in u though) and converts them into molar masses.
