Part A A 360.0 mL buffer solution is 0.130 mol L- in HF and 0,130 mol L-1 in NaF. What mass of NaOH could this buffer neutralize before the pH rises above 4.00? Express your answer using two significant figures. K(HF) = 6.3 x 10-4 ? Submit Request Answer Part B If the same volume of the buffer was 0.360 mol L-1 in HF and 0.360 mol L-1 in NaF, what mass of NaOH could be handled before the pH rises above 4.00? Express your answer using two significant figures. Π ΑΣφ
