Question
0.24g of an organic compound gave 0.287 g of silver chloride in the carius method. Calculate the percentage of chlorine in the compound.
Solution
Mass of organic compound = 0.24 g
Mass of silver chloride = 0.287 g
143. 5 g AgCl contains = 35.5 g chlorine
0.287 g of AgCl contains = `(35.5)/(143.5) xx 0.287`
Percentage of chlorine = `(35.5)/(143.5) xx (0.287)/(0.24) xx 100` = 29.58%
