calculate for strong electrolyte the ph of 0,1M pf HNO3

Please rephrase this question so it makes sense.

To calculate the pH of a strong electrolyte, like HNO3, you need to determine the concentration of the hydrogen ions (H+) in the solution.

In the case of HNO3, it is a strong acid and ionizes completely in water. So, one HNO3 molecule will dissociate into one H+ ion and one NO3- ion.

Given that the concentration of HNO3 is 0.1 M, the concentration of H+ ions in the solution will also be 0.1 M.

Now, to calculate the pH, you can use the formula:

pH = -log[H+]

Substituting the concentration of H+ ions:

pH = -log(0.1) = 1

Therefore, the pH of a 0.1 M HNO3 solution is 1.

Note that because HNO3 is a strong acid, it will dissociate completely, so the concentration of H+ ions will be equal to the initial concentration of HNO3. However, for weak acids or bases, additional steps are required to calculate the pH.
