The GMW of HCl would be the atomic weight of H added to the atomic weight of Cl: H = 1 + Cl = 35.45 = 36.45 g. On solving it gives Mass of NaOH required as 8 grams. This means you need to dissolve 40 g of NaOH in water to obtain a 1 liter of 1M (or 1N) NaOH solution. To calculate the moles, you need the molar mass of NaOH, which is 40 g/mol. The above equation can be used to solve for the molarity of the acid. The mol of NaOH is calculated as moles of NaOH = 4.5 g / 40 (g/mol) = 0.112 mol NaOH The volume 250 ml is equal to 0 .250 L. %PDF-1.5 You are given a 2.3 M Sulfuric acid, H 2 SO 4 solution and a sodium hydroxide, NaOH aqueous solution with an unknown concentration.
