While working in a field hospital you need to determine the concentration of salicylic acid (C7H6O3) in a topical solution. You titrate 1.5 mL of the topical solution with Ba(OH)2 according to the reaction below. The titration requires 6.3 mL of 1.1 M Ba(OH)2 to reach the endpoint. What is the concentration, in molarity, of the salicylic acid (C7H6O3)?
