- A: Your answer has the wrong number of significant digits. - C: Your answer has the wrong number of significant digits. Complete the following table, which lists information about the measured acid dissociation constants of three unknown weak acids. Note: be sure each number you put in the table has the correct number of significant digits. egin{tabular}{|c|c|c|c|} hline acid & ( K_{a} ) & ( mathbf{p} K_{a} ) & relative strength \ hline ( mathrm{A} ) & ( 3 . imes 10^{-2} ) & 1.523 & 1 (strongest) ( vee ) \ hline ( mathrm{B} ) & ( 8.36 imes 10^{-11} ) & 10.078 & 2 \ hline ( mathrm{C} ) & ( 4.3 imes 10^{-12} ) & 11.366 & 3 (weakest) ( checkmark ) \ hline end{tabular}
