How Is The Molarity of A Percentage Solution calculated?
Using 70% concentrated nitric acid as an example: 70% nitric acid means that 100 grams of this acid contains 70 grams of HNO3. The concentration is expressed at 70% wt./wt. or 70 wt. % HNO3. Some chemists and analysts prefer to work in acid concentration units of Molarity (moles/liter). To calculate the molarity of a 70 wt. % nitric acid the number...
What Is The Equation Used For Molarity Conversion?
The 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: [(70 × 1.413) / 63...
