23. A 1.2530 g sample of aniline was diluted with HCl (p = 1.19 g/ml) and a wave of 25 mm in height was obtained on the voltammetric curve. After adding 15.0 ml of a standard nitrobenzene solution with a concentration of 0.5 mg/ml, the wave height increased to 35 mm. Find the mass fraction of nitrobenzene in aniline.
