You must determine the concentration first of the concentrated HCl, typically concentrated HCl is a 36-38% HCL which works out to about 12-12.2 N concentration. From there all you have to due is...
Since hydrogen has an n-factor of 1, its no. of moles and equivalents are same. 0.1 moles 36.5/10 = 3.65 g of HCl. Add 3.65g of HCl to 1 litre of water to get 0.1M or 0.1N solution of HCl.
You can prepare 0.01M HCl from 1M HCl by diluting it with water. To find the amount of water to dilute it with, we use the formula: M1V1=M2V2. If you need 100mL of the 0.01M acid, then we plug in the...
