HÅ V-21.6 4 ml ENC Submit Previous Answers Bequat Answer ? X Incorrect; Try Again; 4 attempts remaining Begin by calculating [OH-] in the final solution using the given pH value. Since KOH is a strong base and completely dissociates into K and OH in an aqueous solution, the molarity of OH equals the molarity of KOH. Finally, rearrange the dilution equation (M₁ V₁M₂V₂) to solve for the initial volume (Vi).

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*]:
