An environmental chemist analyzed the effluent (the released waste material) from an industrial process known to produce the compounds carbon tetrachloride (cc14) 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.
