Chem(ph value and mole)

Question

I know it has some relationship between ph value and mole, please give me these data.

1. ph1=_____mol

2. ph2=_____mol

3. ph7=_____mol

4. ph10_____mol

5. ph14=____mol

And the second question I wanna ask is

Why more acidic substance will have a larger mole?

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&ne;mol????

dun understand=_=

oo..
u wanna ask molarity = mole??

the ans is not~
becoz molarity = mole / volume

/ <--"divide", not "or"

Sorry, I checked the "mol" in the question is the concentration of the hydrogen ion (H+).

the "mol" of hydrogen ion is related to pH value. Isn't it?
