A 360.0 mL buffer solution is 0.160 mol L¹ in HF and 0.160 mol L-¹ in NaF. K. (HF) = 6.3 x 10-¹ Part B If the same volume of the buffer was 0.330 mol L-¹ in HF and 0.330 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. 15. ΑΣΦ m = ? g
