The pH of a 0.94M solution of hydrofluoric acid (HF) is measured to be 1.60. Calculate the acid dissociation constant K, of hydrofluoric acid. Round your answer to 2 significant a K = 0 %3D x10

Each of the four flasks below contains the same volume of .10 M aqueous acid. All four acids are monoprotic, meaning that each acid molecule gives up one H+. The pH of each solution is as indicated.  Flask A: pH=1.1  Flask B: pH=2.4  Flask C pH= 2.9 Flask D: pH=5.1  How much strong base is required to neutralize the initial amount of acid? A. All four solutions will require the same amount of base because they all contain acid of the same concentration B. The solution of pH=1.1 will require the most base since it is the strongest acid and has the highest concentration of H+ C. Neither (A) nor (B) is correct.
