Meer weergeven 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:
