Hello there. I need help with working on some calculations for
two vials (with numbers 3 and 6). We did a lab that measured three
vials. In vial #1, it had a pH of 9, 5 mL of solution was added,
and the moles were 5x10^-8 mol OH-. The actual pH was 6.69 for vial
#1.
Calculate the number of moles of either OH- or H3O+ in
the solution that was added. (OH-) if the solution was a base or...

my main question here is how much do i need to dilute the 10 M
of NaOH woth water in a flask to get the new molarity needed to
complete this experiment?( ive already mixed 25 ml of the unknown
acid with 0.5 ml of the indicator in the volumetric
