mole is not related to pH value..
becoz even a large number of mole, [H3O+] can be low if the volume is much higher than number of mole
(given that molarity = number of mole / volume)
therefore it should be molarity/concentration of H3O+ ion which is related to pH value
u can refer to the following formula
pH = -log[H3O+]
for example, if pH = 2, then [H3O+] = 0.01M, not mol

M≠mol????
dun understand=_=

oo..
u wanna ask molarity = mole??
the ans is not~
becoz molarity = mole / volume
