Consider a buffer solution comprised of HF and F. The K₂ of HF is 6.3 x 10-4. If the pH of the buffer solution is 2.96 and [HF] = 0.115 M, how many moles of F* are present? The volume of the buffer solution is 426 mL. Remember: if you want to express an answer in scientific notation, use the letter "E". For example "4.32 x 104" should be entered as "4.32E4". Answer:
