If the mole of HCl is unkonwn, u ll need a pH meter o something else to determine the pH of the solution first.
By using the formula:
pH = -log(concentration of H+)
then u can get the concentration of H+
HCl is strong acid, so the concentration of H+ equals to the concentrtion of HCl

If you bought it you should be able to trust the label. If it's a diluted solution use a calibrated pH meter.
pH=-log[H+]
HCl is a strong acid so [HCl] = [H+]

[HCl]=moles/volume
no litmus paper is for measuring the pH

Mole/volume, but I think litmus paper works too

concentration = mole/volume
