Question

$0.3780g$ of an organic chloro compound gave $0.5740g$ of silver chlorine present in the compound.

• A. $40$
• B. $37.59$
• C. $25$
• D. $85$

Answer 1

Answer: (B)

$37.59$

Mass of given organic compound $=0.3780gm$

Mass of silver chloride formed $=0.5740gm$

$1$ mole of $AgCl$ contains are mole of chlorine.

So, Mass of chlorine in $0.574g$ of $AgCl=\frac{35.5\times 0.5740}{143.32}=0.1421gm$

Percentage of chlorine $=\frac{0.1421}{0.3780}\times 100=37.59$%
