It is mostly shown in chemical equations by appending (aq) to the relevant chemical formula. The pH was adjusted by addition of aqueous NaOH and HCl stock solutions, and a DLS sample was measured at roughly every 0.5 pH unit interval. 1 m is defined as when one mole of solute is present in 1 kg of the solvent. You correctly converted 500 mL to 0.5 L. Now, we can put the information we already have into the formula. How can molarity be used as a conversion factor? <> The higher molarity of the acid compared to the base in this case means that a smaller volume of the acid is required to reach the equivalence point.
