Subjective Type

0.3780 g of an organic chloro compound gave 0.5740 g of silver chloride in Carius estimation. Calculate the percentage of chlorine present in the compound.

Solution

0.3780 g of organic compound gives 0.5740 g of $$AgCl$$.

143.32g of $$AgCl$$ contains 35.5 g of $$Cl$$.

0.5740 g of AgCl contains $$\displaystyle \frac {35.5 \times 0.5740 }{143.32} = 0.1421 g $$ of chlorine.

The percentage of chlorine in the organic chloro compound is $$\displaystyle \frac {0.1421 \times 100}{0.3780} =$$ 37.6%.
