9. An aliquot of 15 ml of solution was taken from a volumetric flask containing 100 ml of NaOH solution. The titration of an aliquot required 18.5 ml of a standard HCl solution with a concentration c(HCl) = 0.0862 mol/l. Calculate the molar concentration, titer of the HCl solution, and mass of NaOH dissolved in the volumetric flask.
