A 340.0 −mL buffer solution is 0.170 M in HF and 0.170 M in NaF.

Part A

What mass of NaOH could this buffer neutralize before the pH rises above 4.00?

Express your answer using two significant figures.

m =

g

Part B

If the same volume of the buffer was 0.350 M in HF and 0.350 M in NaF, what mass of NaOH could be handled before the pH rises above 4.00?
