3) Consider the following analytical scenario in which case the sample was prepared and analyzed as depicted in the Table below: Volumetric Flask (250 ml) Composition #1 10 ml sample +0 mL of 200 ppm Na+ImL of 0.5% LICI %T - 79.43 #2 10 ml sample + 1 ml of 200 ppm Na+ ImL of 0.5% LICI Abs - 0.12 #3 10 ml sample + 2 ml of 200 ppm Na+ImL of 0.5% LICI %T - 66.06 a) If all the flasks were diluted to a final volume of 250 ml with distilled water, calculate the concentration of Na in the original sample (10 pts) b) Calculate the final concentration of Lici in ppm in each volumetric Mask (5pts)
