In the case of hydrochloric acid, the stoichiometric coefficients of the acid and the hydronium ion are both one. Where: % = Weight %; d = Density (or specific gravity); MW = Molecular Weight (or Formula Weight). Calculate Molarity: moles solute per liter of solution (not volume of solvent added since the solute takes up some space) symbol: M M = moles / liter Molarity is a derived unit (moles/Liter). 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. molarity = 1.04 mol/liter = 1.04 M. "molarity" = "moles of HCl"/"litres of solution" = "12.30 mol"/"1 L" = "12.3 mol/L" Here's a summary of the types of calculations we were using above And here's a video about converting mass % to molarity. Molality, m, tells us the number of moles of solute dissolved in exactly one kilogram of solvent. To do this, multiply the number by 10 6.
