WebFormula to Calculate Molality. It is easy to calculate m if we know the mass of solute and solvent in a solution. Molality is an intensive property, and is therefore independent of the amount being measured. Example 1: Suppose you dissolved 0.5 moles of Sodium chloride in 1Kg of water. Calculate its m. Thus, the molality is 0.5 molal. Example 2: 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:
