List two acids and two bases you come in contact with on a regular basis. which of these is has a ph farthest away from pure distilled water?

10-14. (a) when 100.0 ml of weak acid ha were titrated with 0.093 81 m naoh, 27.63 ml were required to reach the equivalence point. find the molarity of ha. (b) what is the formal concentration of a- at the equivalence point? (c) the ph at the equivalence point was 10.99. find pk. for ha. (d) what was the ph when only 19.47 ml of naoh had been added?

What is the number of moles of chemical units represented by 9.03x10^24? and how do i show work? (dumb it down )
