: An environmental chemist analyzed the effluent (the released waste material) from an industrial process
known to produce the compounds carbon tetrachloride (CCla) and
benzoic acid (HC7H5O2), a weak acid that has one acidic hydrogen
atom per molecule. A sample of this effluent weighing 0.3518 g
was shaken with water, and the resulting aqueous solution
required 10.59 mL of 0.1546 M NaOH for neutralization. Calculate
the mass percent of HC7H5O2 in the original sample.
Ans: 56.82%
