Density of HCl = 1.186 g/mL
Molar Mass HCl = 36.46g/mol
We want a concentration in mol/L so we will first convert density into g/L
(1.186 g/mL)(1000mL/1L) = 1186 g/L
We must now know what density 37% of that is
(0.37)(1186 g/L) = 438.82 g/L
Now divide this density by the molar mass to cance out the g and give you mol/L (concentration)
C = (438.82g/L)/(36.46g/mol)
C = 12.04 M
Since HCl is monoprotic, 1M = 1N.
Therefore, 37% HCl is ~12N
To find the normality of a solution, you need to know the molarity and whether the solution is monoprotic or polyprotic. Since fuming HCl is typically monoprotic (one hydrogen per molecule), you can assume the normality is equal to the molarity. Therefore, the normality of a 37% fuming HCl solution is approximately 11.1 N (since 37% is roughly 11.1 M HCl).
To prepare 0.5N HCl from 37% HCl solution, you can use the formula C1V1 = C2V2 where C1 is the initial concentration, V1 is the initial volume, C2 is the desired concentration (0.5N), and V2 is the final volume. Calculate the volume of 37% HCl needed and dilute it to the desired volume with water.
Depending if you want your % to be in volume and you have 100 mL then add 212.5mL to the HCl. If you want it by mass and you have 100g of HCl then add 212.5 g of water which is about 212.5 mL anyways. #swag
Try a gradual measuring pipet max. 100 mL from which you'll get 83 (+/- 1) mL. More accurate then this is not easily done and besides that it's also not usefull: the given concentrated 37% is also accurate between 36% - 38%, so you'll never get an exact 1.00 N HCl.
To make 5N HCl solution, add the appropriate volume of concentrated hydrochloric acid (usually around 37% concentration) to water to achieve the desired normality. Use proper safety precautions as hydrochloric acid is corrosive and should always be added to water, not the other way around, to avoid splattering. It's recommended to double-check calculations and volumes to ensure accuracy.

To convert 37% to decimal divide by 100: 37% ÷ 100 = 0.37
To convert 37 to percent multiply by 100: 37 × 100 = 3,700%
The standard normality of HCl is 11.3 N because it is a strong acid with one hydrogen ion, which means that one mole of HCl will dissociate into one mole of hydrogen ions. Normality is a concentration unit that takes into account the number of equivalents of the solute in a solution. For HCl, the equivalent weight is equal to the molar mass, which is 36.46 g/mol, so 11.3 N corresponds to 11.3 moles of HCl per liter of solution.
To convert 37 hundredths (0.37) to percent, multiply by 100: 0.37 × 100 = 37 %
To prepare 0.5N HCl from 37% HCl solution, you can use the formula C1V1 = C2V2 where C1 is the initial concentration, V1 is the initial volume, C2 is the desired concentration (0.5N), and V2 is the final volume. Calculate the volume of 37% HCl needed and dilute it to the desired volume with water.
Put it over 100. 37% = 37/100
To convert 0.370 to percent multiply by 100:0.370 × 100 = 37 %
Acid solutions are typically made in laboratories from commercially available acids which are supplied with specifications as to their physical and chemical properties including their concentrations. Calculations: For example, if you wish to use concentrated HCl that just arrived in your lab yesterday to make (say) 1N HCl, you will need to know the normality of the available solution. Suppose you know that it is 37% HCl (and all other information is missing); this means 37 mL HCl in 100 mL solution, M.W. of HCl = 36.5, Density = 1.185; 1.185 g HCl occupies 1 mL volume, 37 mL HCl corresponds to 43.84 g HCl. If the commercially available solution is 43.84 g HCl in 100 mL solution and you know that 36.5 g HCl in 1000 mL solution makes 1N (also 1M HCl) solution, then you have a 12N (also 12M) solution in your hands. So that means you must dilute it 12 times to get a 1N HCl solution. Titration: If you don't have a new solution at hand and are not sure about how correctly the HCl reagent was stored over many years, it would be prudent to measure the concentration of acid by titration provided you have fresh (reliable) base solutions at hand and reliable indicators.
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.
