0 . 25   g of an organic compound containing chlorine gave 0 . 40   g of silver chloride in Carius estimation. The percentage of chlorine present in the compound is [in nearest integer] (Given: Molar mass of Ag is 108   g   mol - 1 and that of Cl is 35 . 5   g   mol - 1 )

Step-by-step solution

Percentage of chlorine in the organic compound= atomic   mass   of   chlorine   X   mass   of   AgCl   formed   X   100 molecular   mass   ofAgCl   X   weight   of   organic   compound Mass of organic compound = 0 . 25   g Mass of AgCl formed = 0 . 40   g Mass of Cl in organic compound = 0 . 40 × 35 . 5 143 . 5 × 0 . 25 Percentage of Cl in the compound = 0 . 40 × 35 . 5 143 . 5 × 0 . 25 × 100 = 39
