Webin terms of parts per million (ppm) or parts per billion (ppb) because the amounts are so small. For example, a concentration of 1 ppm corresponds to 1 part material per 1 million parts of the gas, liquid or solid it is found in. In the case of ppb, the same relationship exists: 1 part material per 1 billion parts of a gas, liquid or solid. WebThe following equation is used for calculating acid and base molarity where the concentration is given in wt %: [ (% × d) / MW] × 10 = Molarity. Where: % = Weight %; d = Density (or specific gravity); MW = Molecular Weight (or Formula Weight). The above equation can then be used to calculate the Molarity of the 70 wt % Nitric Acid: jemd internationalhttp://scientifictutor.org/838/using-stoichiometry-in-conversions/ jemd cef
