How can 1 M of HCl be prepared from 32 percent HCl concentration?

percentage = well, mostly weight percentage is the most commonly given percentage density = the density of a sol'n is constant, for HCl, the value is 1.18 g/ mL now assuming you have 34% of HCl in the sol'n in preparing 1M HCl, calculate the mass of HCl Needed.
assuming there are 100g of the whole solution, therefore there will be 34g of HCl:
percent by weight = (34% x 100g) / 100g
= 34g
now to get the mass, we need dimensional analysis. 34 g HCl x 1 mol HCl x 1 L sol'n x 1.18 g HCl x 1 mL = FINAL ANSWER
36.45 g HCl 1 mol HCl 1 mL 1 L sol'n you just get the final answer.... percentage = well, mostly weight percentage is the most commonly given percentage density = the density of a sol'n is constant, for HCl, the value is 1.18 g/ mL now assuming you have 34% of HCl in the sol'n in preparing 1M HCl, calculate the mass of HCl Needed.

How many gallons of HCL Acid in a ton?
Depends on the concentration of HCL but 255 to 264 gallons
How do you prepare 1.5M HCl from 32 percent HCl?
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.
For Kovac's reagent what concentration of hydrochloric acid do you use?
Most recipes just specify 'concentrated' HCl. That could mean 32 % or 37 %. One or two specify 32 %. Now, HCl 32 % w/w = 37 % w/v and HCl 37 % w/w = 44 % w/v, and since the HCl in Kovacs Reagent is mixed 1:3 (by volume) with isoamyl alcohol, the final concentration of HCl will be 9.25 % w/v or 11 % w/v respectively. Further, some recipes specify a 1:3 mixture by mass - resulting in proportionally much less HCl. So it's not critical. I'm using 32 %.
What is the molarity of 32 percent HCl?
A: 10.172 M HCl. Percents of acids like this one is normally given in % w/w, or percent weight by weight. So we need to find the mass of the solution. Molarity is moles of solute per liter solution, so we will calculate this for 1L of solution. The density of 32% HCl is 1.159 g/mL. So assuming we have one liter or 1000 mL, the weight of the solution is 1159 g. If 32% of this is HCl, we have 1159 g solution * 0.32 g HCl/g solution = 370.88 g HCl. The molar mass of HCl is 36.461 g/mol, so 370.88 g HCl * 1 mol HCl/36.461 g HCl = 10.172 mol HCl in 1 L of solution. 10.172 mol HCl/1L solution = 10.172 M HCl.
How do you make a Molar solution from 32 percent hydrochloric acid?
32% hydrochloric acid is 10.2 M. You must dilute it to the desired molar concentration. For safety, be careful to add the acid to water and to wear appropriate protection.
