First look at the Related Question about how to determine the pH of a strong acid to determine the concentration of acid required to get a pH of 4. Just work backwards from the way the examples are done to find the concentration you need
Then look at the Related Question about how to make a solution of a certain concentration by diluting another solution (assuming you make the HCl solution from a concentrated stock solution).
See the Related Questions to the left for the answer.
To make 4N HCl from concentrated HCl, you can dilute the concentrated HCl with water in a ratio that will give you a final concentration of 4N. For example, to make 1L of 4N HCl, you would mix 273 ml of concentrated HCl (37% w/w) with 727 ml of water. Always remember to add acid to water, not the other way around, and wear appropriate safety gear when working with concentrated acids.
To prepare 4N potassium chloride solution, dissolve 149.5 g of potassium chloride in 1 liter of water. This will give you a solution with a concentration of 4N. Make sure to use a balance to accurately measure the amount of potassium chloride needed.
To prepare 6N HCl from 1N HCl, you can dilute the 1N HCl by adding 6 times the volume of water to the 1N HCl solution. For example, mix 1 volume of 1N HCl with 6 volumes of water to get a final concentration of 6N HCl. Make sure to add acid to water slowly with stirring to avoid splashes and heat generation.
44.5 ml HCl TAKE AND DILUTE UP TO 1000 ML WATER MAKE A 0.5 M HCl SOLUTION
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.

100 M HCl don't exist.
To prepare 6N HCl from 1N HCl, you can dilute the 1N HCl by adding 6 times the volume of water to the 1N HCl solution. For example, mix 1 volume of 1N HCl with 6 volumes of water to get a final concentration of 6N HCl. Make sure to add acid to water slowly with stirring to avoid splashes and heat generation.
520 ml of HCl in 480 ml of water=1000ml = 5 N
1.21 g Tris-HCl, QS water to 1L. Scale appropriately.

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.
To prepare 0.1M Tris-HCl, dissolve 1.21 g of Tris (molecular weight 121.14 g/mol) in distilled water to make 100 mL of solution. Adjust the pH to 7.4 using HCl.
To prepare a hydrochloric acid (HCl) solution, you can dilute concentrated hydrochloric acid with water. Always add the acid to water slowly while stirring, never add water to acid, as it can cause splattering. Be sure to wear appropriate protective gear and work in a well-ventilated area when handling HCl.
To prepare 0.02N HCl solution, you would need to dilute a more concentrated HCl solution with water. Calculate the volume of concentrated HCl needed using the formula C1V1 = C2V2, where C1 is the concentration of the concentrated HCl, V1 is the volume needed, and C2 is the desired concentration (0.02N). Dilute the calculated volume of concentrated HCl with water to reach the desired final volume.
To prepare a 1.3N HCl solution, you would need to dilute concentrated hydrochloric acid (usually 37% HCl) with water in a specific ratio. Measure out 1.3 moles of HCl in a specific volume and then dilute it to the desired final volume with water. Make sure to handle concentrated HCl with caution and follow proper safety protocols.
