Using the information below, calculate the percentage w/V of lidocaine (MM (234-34 g/mol) in Lignocaine Oral Topical Solution. Show your reasoning clearly and record your final answer to three significant figures. dire Assay - "Transfer an accurately measured volume of Oral Topical Solution, equivalent to about 150 mg of lidocaine, to a 125 mL conical flask, and protect from atmospheric moisture with a stopper fitted with a tube containing Lidocaine silica gel. Add 20 mL of glacial acetic acid and 2 drops of crystal violet TS. Titrate immediately with 0.1 M perchloric acid VS to a blue endpoint. Perform a blank titration, and make the necessary correction." Results: • Amount of topical solution measured = 7.5 mL • Concentration HCIO, = 0.09998 M Volume titrated 6.99 mL Volume blank titration = 0.65 mL
