Question: Calculate the pH of 0.15 m H2SO4(aq) at 25 degrees Celsius.

How would you know that the initial concentration of H30+ is also 0.15 mol/L? Thank you!

Would this be due to H2SO4 being a strong acid? so H3O+ would be the same value since it was completely dissolved

H2SO4 is a strong acid and is fully ionized. Therefore, if the concentration of H2SO4 is 0.15 M, then the concentration of HSO4- and H3O+ would both have a concentration of 0.15 M.
