HCl is usually prepared by dissolving Hydrogen Chloride into water, but as we increase the concentration of HCl its boiling point starts to decrease (10% HCl has boiling point of 103 C and 38% has 48 C), so at concentration over 38 the rate of evaporation becomes so high that extra precautions has to taken for storage and handling (like low temperatures and high pressure), Thats why it is not safe to produce HCl over 40%. And as the rate of evaporation at even 38% is quite high it is called fuming HCl acid.
The normality is 10,8.
Prepare HCl 1 M by HCl concentration 37 % HCl concentration 37 % have density =1.19 g/ml HCl 1 M use HCl 37 % 82.81 ml make volume with water to 1 liter
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
37% HCL equals to 12.18 M. So you can caculate 32% is 10.53 M. That means for preparing 1 L 1.5 M HCL, you need mix 142.45 mL 32% with 857.55 mL dH2O.
I'm not sure about the 37 thing but here is from NIOSH method in how to prepare 6N HCL -pipette 25.64 mL of 11.7 N (37% HCL fuming) to 50 mL volumetric flask and top up with distilled water GOOD LUCK Always add acid to water.
i dont knw

Take 78.4ml of deionized water by adding 26.1ml of concentrated HCL (11.6N) and mix uniformly. Prashant W Jalna ( Maharashtra , India)
37 percent.
37% HCl = { [ 37 (gHCl) / 100 (g sol'n) ] / 36.46 (gHCl/molHCl) } * 1,18 (g sol'n/mL sol'n) * 1000 (mL/L) = about 12 M HClTo prepare V Litres of 10M sol'n you should dilute [10*V]/12 Litre of 37% HCl solution to the total volume of V. Be very carefull with this addition of water.
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.
37 percent in fraction = 37/10037% = 37%/100% = 37/100 in fraction
37.5 percent is larger than 37 percent.
