Answer:
The pH of the solution is 3.51.
Step-by-step explanation:
To calculate the pH of a solution containing 0.1 mol of H+ in 325.7L of water, we need to first calculate the concentration of H+ in the solution.
Concentration (in mol/L) = Number of moles / Volume (in L)
Concentration (in mol/L) = 0.1 mol / 325.7 L
Concentration (in mol/L) = 0.000307 mol/L
Now, we can use the formula for pH:
pH = -log[H+]
where [H+] is the concentration of hydrogen ions in the solution.
Substituting the value of [H+] we calculated above, we get:
pH = -log(0.000307)
pH = 3.51
Therefore, the pH of the solution is 3.51.
