8. A sample of steel weighing 0.6000 (g) was dissolved in a 50.0 ml flask. Aliquots of 20.0 ml were taken into two 50.0 ml measuring flasks. A solution containing 0.001200 g of titanium was added to one flask. Hydrogen peroxide was added to both flasks and the solutions were brought to the mark. Calculate the mass fraction (%) of titanium in the steel if the following optical densities were obtained during photometry of the solutions: Ax = 0.230 and Ax + st = 0.465.
