Question

0 . 25 &#160; g of an organic compound containing chlorine gave 0 . 40 &#160; 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 &#160; g &#160; mol - 1 and that of Cl is 35 . 5 &#160; g &#160; mol - 1 )

Aicharya · Accepted Answer

Percentage of chlorine in the organic compound=

\frac{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 $= \frac{0.40 \times 35.5}{143.5 \times 0.25}$

Percentage of $Cl$ in the compound $= \frac{0.40 \times 35.5}{143.5 \times 0.25} \times 100$

$= 39.58 %$

Nearest integer=40.
