What is the pH of a buffer prepared by adding 0.809 mol of the weak acid HA to 0.507 mol of NaA in 2.00 L of solution? The dissociation constant K₂ of HA is 5.66 × 10-7. Express the pH numerically to three decimal places. ► View Available Hint(s) pH = 6.044 Submit Previous Answers Correct Since both the acid and base exist in the same volume, we can skip the concentration calculations and use the number of moles in the Henderson- Hasselbalch equation to calculate the pH. The answer will be the same.
It says that my answers are wrong but it won’t tell me what answers are wrong I thought I did it right please help me.
