![]() 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.

By using this handy metals calculator, you can calculate the weight of any wax model in any of the metals we cast. ![]() 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 ). During 15th Century England, the weight of an English penny was exactly 1/20th of a troy ounce and 1/240th of a troy pound of sterling silver. This page uses the conversion rate from talents to kilograms, and from talents to shekels listed below, and the todays market prices for gold and silver shown below, to calculate the values.
