since all of these are strong acid and strong base, all u have to do for each question is to take the -log of the Molarity.
For example, for a) enter -log (1.0) into your calculator and the calculator will give u an answer. Do the same thing for every problem.

Well,
To determine the pH. All you have to do on your calculator is type in the -log (H+) the H+ is the molar concentration or M or mol/L, etc. This will tell you the pH. pH 7 is neutral, anything from 7-14 is basic, 14 being the strongest base. And 7-0 is acidic 0 being the strongest.

u must know the constanta first..
the weak acid, such as nitric acid needs that..
