The first step is calculating the number of moles of solute present. If you have dissolved 1 g of NaOH in enough water to make a total of 250 ml of solution, calculate the number of moles of solute present by diving the mass of NaOH by the molecular mass of the compound. The molecular mass of NaOH is 40, so work out 1 ÷ 40 = 0.025.

Hydrochloric acid 1 N, Reagent Grade. Hydrochloric acid. Formula: HCl MW: 36.46 g/mol Storage Temperature: Ambient: MDL Number: MFCD00011324 CAS Number: 7647-01-0
For hydrochloric acid (HCl) the equivalent weight is 36.46 grams. Therefore, for making an 1 Normal solution, 36.46 g/liter of HC1 is needed. Note that a 1 M solution is also 36.46 g/L. For molecules that can give off or accept only one proton per molecule, the Normality is equal to the Molarity. Table 1.
0.2 N HCl solution means 0.2 equivalents of HCl dissolved in 1 litre of water. Normality = Molarity x n-factor => Molarity =Normality/n-factor=0.2/1=0.2 M 0.2 moles should be present in 1 litre of solution. 0.2moles =0.2 x 36.5 = 7.3 grams of HCl =>Dissolve 7.3 grams of HCl in 1 litre if water to get a 0.2N solution.

Preparation and Standardization of 0.1 M Hydrochloric acid (HCl) Take about 100 ml of water in a cleaned and dried 1000 ml volumetric flask. Add about 8.5 ml of Conc. Add more about 700 ml of water, mix and allow to cool to room temperature. Make up the volume 1000 ml with water.
In simple words, the number of gram equivalents of solute dissolved in per litre of the solution. It is denoted by N. It is used for acid or base solution. For units of concentration, the symbols N, eq/L, or meq/L (= 0.001 N) are used. For example, 0.1 N HCl could be used to describe the concentration of a hydrochloric acid solution. es1Y2Z6.
