\(0.25\, g\) 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 \(35.5 \,g\, mol ^{-1}\) )
- A \(40\)
- B \(140\)
- C \(80\)
- D \(143\)
Answer & Solution
Correct Answer
(A) \(40\)
Step-by-step Solution
Detailed explanation
wt. of organic compound \(=0.25 \,g\) mass of \(Cl =\frac{35.5}{143.5} \times 0.4\, g\) mass \(\%\) of \(Cl\) in the organic compound \(=\frac{35.5 \times 0.4}{143.5 \times 0.25} \times 100\) \(=39.58 \,\%\)
