Previous Answers
Correct
Term 2: Correct answer is shown. Your answer 4.57-10-11 = 4.57x10-11 M was either rounded
differently or used a different number of significant figures than required for this part.
Important: If you use this answer in later parts, use the full unrounded value in your calculations.
KOH is a strong base that completely dissociates into K+ and OH in an aqueous solution:
KOH(aq) → K*(aq) + OH- (aq)
Therefore, the concentration of OH is the same as the given concentration of KOH and is equal
to 2.2 x 10-1 M. Then use the ion product constant, substitute the calculated value for OH,
and solve for (H3O*]:](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fe17ee3d9-6ebe-435a-ba9d-3c68c44204c7%2Fd39c9cd2-724e-42fb-bab4-e13f0def3b50%2Fen1078_processed.jpeg&w=3840&q=75)
