HCl is a strong acid and dissociates completely. Therefore it can be found using the equation:
ph= -log [H+]
The pH is the negative log of [H+].
pH = -log10 [H+] you need to know the number of moles of hydrogen ions in your sulphuric acid. for example if you have a 0.25M solution of sulphuric acid, you will have 0.5moles of hydrogen ions (provided your acid id fully dissociated!)
In order to calculate the pH of a weak acid using only molarity, one would have to look up the acid equilibrium constant (Ka) of the acid. Then one could use the equilibrium expression Ka = ([H+]x[B-])/[HB] to solve for the concentration of the H+ ion. Using this value with the equation pH = -log10[H+] will give the pH of the solution.
Molar mass tells you nothing about what the pH of a solution will be. You need to know its pKa or pKb, and how much solute is being put in how much solvent, as well as what other chemicals are being put with it.
The sulfuric acid molecule is made up of two hydrogen atoms, one sulfur atom and four oxygen atoms. Their atomic masses are 1, 32 and 16 respectively. The molecular mass of sulfuric acid is 2x1+32+4x16=98u.
You need to know the molar mass of this acid, the total mass of the acid and the volume of solution.
Content of the acid in 1 L is: total mass in g /volume of solution in L
Molarity is: content of the acid in 1 L/molar mass
if you are given X number of moles, denoted as X, you take -log(X).
Find litmus paper, I believe its called
pH is -log[H+] and can be found using pH meter.
This is the concentration of the ion H+.
pH = -log10[H+], where [H+] is the hydrogen ion concentration. So, in this case, pH = -log10[1], yielding pH = 0.
The hydrogen ion concentration in mol/L
Can use this way. -log(0.001) = 3 14 - 3 = a pH of 11.0
The pH is the negative log of [H+].
pH is -log[H+] and can be found using pH meter.

You usually calculate it with a pH stick. Good question!!.
This is the concentration of the ion H+.
Sodium chloride solution is neutral.
-log[H+] = pH therefore -log[0.001] = 3.00 The pH of a solution of 0.001 mol dm HC1? is 3.00
pH= -log = 1.59
This depends on what other acids or bases or buffering substances are in solution already, even if pH is neutral!
The molar concentration of the hydrogen ions
In an aqueous solution, the concentration of H3O+ is the same as the concentration of H+. If you know the pH of the solution, then that's equal to 10^(-pH).
pH = -log10[H+], where [H+] is the hydrogen ion concentration. So, in this case, pH = -log10[1], yielding pH = 0.
