MCQ
In Carius method $0.099 \,g$ organic compound gave $0.287\, g$ $AgCl$. The percentage of chlorine in the compound will be
  • A
    $28.6$
  • $71.7$
  • C
    $35.4$
  • D
    $64.2$

Answer

Correct option: B.
$71.7$
b
(b) $\%$ of chlorine = $\frac{{35.5}}{{143.5}} \times \frac{{{\rm{Mass\, of }}\,AgCl}}{{{\rm{Mass \,of \,substance}}}} \times 100$

= $\frac{{35.5}}{{143.5}} \times \frac{{0.287}}{{{\rm{0}}{\rm{.099}}}} \times 100 = 71.71\% $.
