Take 100 grams of 36% HCl-sol'n and add it up with (260 g) water to total weight of 360 gram 10% HCl-sol'n.
Don't use volumetrics, because the density is not linearally changing and there is no 'Law of conservation' for 'volumes' (only for mass).
Oh, dude, it's simple! To make 2M HCl in 100ml from 36% HCl, you'd need to dilute the 36% HCl with water. Just mix 5.56ml of 36% HCl with 94.44ml of water, and voila, you've got yourself some 2M HCl. It's like making a fancy cocktail, but with chemicals!
About 13M. You can assume it is 13M if you don't need an exact concentration (like if you need a ~1M HCl solution for an extraction or whatever) but if you need an exact concentration (for a titration, for example) then you will need to standardize your HCl first.
Hydrochloric acid, HCl, is composed of one hydrogen atom and one chlorine atom. Therefore, the percent of hydrogen in hydrochloric acid is approximately 1/36 or 2.78%.
To dilute 36M HCl to make 1M HCl, you need to add 1 part of 36M HCl to 36 parts of water. So, for example, if you want to make 1 liter of 1M HCl, you would mix 27.8 ml of 36M HCl with 972.2 ml of water. Always remember to add acid to water slowly and with stirring to prevent splattering.
To prepare a 1N solution of 35.4% HCl, you need to first calculate the molecular weight of HCl, which is 36.46 g/mol. Next, calculate the weight of HCl needed to make 1L of 1N solution using the formula: weight (g) = Normality (N) x Equivalent weight (g/mol) x Volume (L). Finally, dissolve this weight of HCl in enough water to make 1L of solution.
To convert a fraction to percent multiply by 100 % 36/240 × 100% = 15% → 36 is 15% of 240.
36% in fraction = 36/100 or 13/50
equals o.36 or 36/100 = 9/25

To find 36 percent of 850, you first convert 36 percent to a decimal by dividing it by 100, which gives you 0.36. Then, you multiply 0.36 by 850 to get the answer. Therefore, 36 percent of 850 is 306.
10/36 = 5/18 = 0.277 = 28%
To convert 0.36 to percent multiply by 100: 0.36 × 100 = 36%
To find 10 percent of 360 degrees, you can multiply 360 by 0.10 (which is the decimal equivalent of 10 percent). This calculation gives you 36 degrees, which represents 10 percent of the total 360 degrees in a circle. So, 10 percent of 360 degrees is 36 degrees.

To convert a percentage to a decimal, divide the percentage by 100. 36 / 100 = 0.36
