Look up the molar mass of HSO, then compare it to 20% of 196 g; by dividing appropriately, find how many moles of HSO there are. Molar mass NaOH ( sodium hydroxide) = 40.0 g/mol Number of moles: n = mass / molar mass n = 10.0 / 40.0 n = 0.25 moles Volume = 2.0 L Molarity = number of moles / volume in liters M = 0.25 / 2.0 M = 0.125 M answer D hope this helps! Molarity = 0.15 moles of KMnO 4 /0.75 L of solution. Hence, increasing the molarity of an acid will decrease its pH value. Using this, you can easily compute the number of moles of NaOH needed. Add sodium hydroxide to water do not add water to solid sodium hydroxide. Solution density measured at 15.56C = 60F. The molarity of a sodium hydroxide solution is 0.2 M. The molar mass of NaOH is 40 g/mol. Example: 0.8 grams of KHP is titrated with 40 ml of the unknow n NaOH solution. I'll assume that one mole of sodium hydroxide is required to neutralize one mole of potassium hydrogen phthalate, since I don't think hydrogen phthalate exists by itself! 2 Procedure There are various components to this procedure. Explanation: Molarity is a concentration term in which the no. Answer (1 of 11): For the preparation of 10% Sodium Hydroxide (NaOH) solution follow that steps * (% age = [(required mass)/total mass]x100 10 % = [required mass/ 100]x100 Percent mean in 100 so, total mass is 100 So, required mass = 10 g) * Since it is one mole of HCl react with one mole of NaOH, you can simplify the equation as : M1 x V1 = M2 x V2.
