Normality is the number of gram equivalents of solute per liter of solution.
N = [ ( m ) / ( M ) ( Z ) ] [ 1000 / V in mL ]
where Z represents the number of H+ ions that the one molecule of the solute is capable
of releasing or reacting with. For HCl, Z = 1 .
N = [ ( 3.65 g ) / ( 36.458 g / mol ) ( 1 ) ] [ 1000 mL / 1000 mL )
N = 0.100 N <--------------------
The normality of the solution is 0.125 moles in the solution.
Hydrochloric acid can be measured in units of concentration, such as molarity (moles per liter) or normality (equivalent grams per liter). It can also be measured using pH, which indicates the acidity or alkalinity of a solution, or by titration with a suitable base to determine its concentration.
3.8 grams of EDTA salt in 1 liter of DI water made up using a volumetric flask will give you 0.02n or 0.01m of EDTA solution. normality*eq.wt*volume rqrd weight= 1000 then will get weight of the compound required for that normality
HCl has a molar mass of 36.461 grams per mole. This means that 72.922 grams of HCl are needed per liter of water to make a solution that has a concentration of 2M.

The N of 0.02 N acid stands for the "normality". The normality is defined as the gram equivalent weight of a substance in a liter of solution. so, a 0.02 acid would have 0.02 gram equivalents of acid per liter. In short N means "normality" and stands for "g/l"

The normality of commercial grade hydrochloric acid (HCl) can vary depending on the concentration specified by the manufacturer. Hydrochloric acid is commonly available in different concentrations, such as 37% or concentrated hydrochloric acid. To determine the normality, it is essential to know the molarity (moles of solute per liter of solution) and the number of equivalents of the acid. Normality (N) is related to molarity (M) by the equation: � = � × � N=n×M where: � N is the normality, � n is the number of equivalents, � M is the molarity. For hydrochloric acid (HCl), which is a monoprotic acid (donates one proton), the number of equivalents ( � n) is equal to 1. Therefore, if you know the molarity of the commercial grade hydrochloric acid, you can determine its normality using the equation mentioned above. It's important to check the product label or contact the manufacturer for the specific concentration of the hydrochloric acid you are using.

Is the makeup of the solution expressed as "percent by mass"? If so, to calculate molarity (or normality), you have to also know the density of the solution Step 1. Lets say the solution is 14%, and the density is 1.09 g/mL. We can write the following: (14 grams solute/100 grams solution) (1.09 grams solution/ mL solution) Step 2. Multiplying and cancelling from step 1 gives you 15.26 grams solute / 100 mL solution. Multiplying top and bottom by 10 gives you 152.6 grams solute per liter. Step 3. Molarity is number of moles per liter. Divide the 152.6 grams of the solute by the forumua weight (or molecular weight) of the solute, and you have the number of moles of solute. This number is therefore the molarity of the solution. If the solution is "percent by volume", the number you have is number of grams per 100 mL. Multiply by 10, and you have grams per liter. Then divide by the formula weight, and you have the molarity.
HCl has a molar mass of 36.461 grams per mole. This means that 72.922 grams of HCl are needed per liter of water to make a solution that has a concentration of 2M.
The normality of a solution is the gram equivalent weight of a solute per liter of solution. For example, 1 M sulfuric acid (H2SO4) is 2 N for acid-base reactions because each mole of sulfuric acid provides 2 moles H+ ions.
The molarity of a solution is the number of moles of a solute per liter of its solution. The normality of a solution is the number of gram equivalent weight of a solute per liter of its solution. As I said before, and precisely, Molarity is moles of solute per VOLUME of solution!
30 liters
2 moles of HCl for every liter of solution.
The N of 0.02 N acid stands for the "normality". The normality is defined as the gram equivalent weight of a substance in a liter of solution. so, a 0.02 acid would have 0.02 gram equivalents of acid per liter. In short N means "normality" and stands for "g/l"
try adding ten grams to every liter
One liter of Benedict's solution contains 173 grams sodium citrate, 100 grams sodium carbonate, and 17.3 grams cupric sulfate pentahydrate.
