Finishingconcentrations in K in one tablet. 20 tablets are weighed (35.6751 g) and reduced in powder. A small amount of this powder (0.1338g) was dissolved in 500 mL of deionized water.5 mL of this solution was pipetted and inserted into a volumetric balloon and the volume was completed at 100 mL. The spectrophotometer provided an emission signal equal to 73.9.In addition, a standard solution was prepared, dissolving 0.1912g of KC1 in 100 mL of deionized water.5mL of this solution was pipetted and inserted into a volumetric balloon and the volume was completed at 250 ml This solution was used to prepare a calibration curve using; 5-10-15-20-25 mL: Solution 0 A B C D And Volume prepared 0 5 10 15 20 25 solution (mL) Deionized Complete up to measurement stroke (100 mL) water Solution 0 A B C D And K+ emission 0 20,3 40,1 60,3 80,1 100 signal What is the mass of KC1 per tablet?
