(12 M HCl )(X ml) = (1.50 M HCl )(4.00 L HCl )
12X = 6
X = 0.50 Liters ( which you add to 3.5 Liters water )
The needed volume of concentrated acid is 113,6 mL.
WE NEED 819.672 ML OF Concentrated HCL

Method: titration with a standardized solution of sodium (or potassium) hydroxide.
Aqua regia (mixture of concentrated nitric acid and hydrochloric acid). However, nitric acid and hydrochloric acid by themselves don't dissolve gold.
Multiply .3631 and 1.185 together and take that answer and multiply it by 175. That's your answer.
A solution that contains a large amount of solute when compared to the volume of the solvent is called a concentrated solution. Examples of concentrated solutions are hydrochloric acid and sulfuric acid. A dilute solution is one where the amount of solute is small compared to the solvent.
Concentrated HCl is hydrochloric acid with a concentration that is close to the maximum amount of this acid that can be dissolved in water. In general, it is considered to be approximately 12M, which is 12 moles of acid per L of solution, however 38-40% acid solution of concentrated HCl do exceed 12M (up to 12.6M). I am not sure of what happens if you try to make a solution of HCl that is more concentrated. In any case, you should always read the label on the bottle and consider the age of the mixture as pure HCl is a gas and will evapourate, which will lower the concentration.

Any concentration is possible to be prepared; the concentrated acid has generally a concentration of 36,5 % (36,5 g HCl in 100 mL water solution).
Hydrochloric acid is a mixture, generally HCl + water.Note that in English HCl (pure, as a gas) is called hydrogen chloride.

Examples: - concentrated solution of sulfuric acid - concentrated solution of nitric acid - concentrated solution of ethanol - concentrated solution of sugar (syrup) - concentrated solution of table salt

Drinking squash, concentrated vegetable boullion (stock), some fruit juices are concentrated then diluted again... basically anything that has been boiled to remove the water content is "concentrated".
