74.5513 g/mol KCl * * 1 mol/eq * 0.1 eq/L = 7.455 g/L
So accurately weight 7.455 g dry, analytical grade KCl and dissolve in volumetric flask of exact 1.000 Liter and fill up with water to the 1L-mark, close and carefully mix by repeated inversion. In this way you can get an exact 0.1000 N KCl standard solution.
0.01M ammonium hydroxide (NH4OH) is a concentration of 0.01 moles NH3 in 1L of water (out of solution NH4OH does not exist, it is just ammonia: NH3).
NH3 has a molecular weight of 18 g/mole, so 0.01 moles is 0.18 g. Placing 0.35g of NH3 in 1L water will give a 0.01M solution of NH4OH.
I believe the problem is on the normality unit since the preparation of standard solution in unit of mol is a simple mathematics. Sodium hydroxide (NaOH) had OH as functional group and is only 1 per active molecules. The Normality of 0.02 N is then equal 0.02 mol/L.
Preparing 0.02 mol/L is best start at 1 mol/L standard solution by dissolve 40 g of NaOH pallets to 1 L of distilled water in volumetric flask (NaOH is 39.997 g/mol). Then pipette out 20 ml of 1mol/L solution into 1000 mL volumetric flask. Add up with distilled water until it reach the mark and you got yourself a 0.02 N sodium hydroxide solution.
Please handle NaOH with care.

Potassium hydroxide
Potassium hydroxide is used to prepare only liquid soaps. Soaps resulted from the saponification of fats with KOH are liquids or viscous. Soaps resulted from the saponification of fats with NaOH are solids.
The formula "K" refers to potassium hydroxide. When dissolved in methanol (OH), it becomes KOH, or methanolic potassium hydroxide. This is an extremely volatile liquid, so the utmost care must be taken in preparation.
potassium hydroxide is a base. anythng with hydroxide at the end is an alkali
Potassium hydroxide is not a natural product.
A mil is a measurement that equals one-thousandth of an inch, or 0.001 inch.
KOH is potassium hydroxide, its common name is caustic potash or potash lye.
