In the 19boratior, a general chemistry suoent measpred the oll of a \( 0.516 \mathrm{~N} \) aquesus solutoin of hydrocyanic acid to tan \( 4.876 \) Wse the intormation she otcaines to oetermine the K, for this acid \[ \text { Kytexperiment) }= \] Use the References to access important values if needed for this question. In the laboratory, a general chemistry student measured the \( \mathrm{pH} \) of a \( 0.516 \mathrm{M} \) aqueous solution of benzoic acid, \( \mathrm{C}_{6} \mathrm{H}_{5} \mathrm{COOH} \) to be \( 2.261 \) Use the information she obtained to determine the \( \mathrm{K}_{\mathrm{a}} \) for this acid. \[ K_{a}(\text { experiment })= \] 1 more group attempt remaining
