What mass of KOH would need to be dissolved in 500.0 mL of water to produce a solution with a pH of 12.40?

Answer 1

Hi Cole B.,

Looks like you submitted all your problem set -- 7 questions on simple acid-base equilibria -- at once. That's spamming. Please submit a single question per topic or calculation type, then digest the answer. Please don't waste Ask an Expert time; if you are at square zero on your chemistry, find a regular Wyzant tutor for a bit?
