0.3780 gm of an organic chloro compound gave 0.5740 gm of silver chloride in Carius estimation. Calculate the percentage of chlorine present in the compound (in nearest integer).(If answer is X, then enter $$\dfrac X6$$)

A
B
C
D

Solution

Percentage of CI $$=\displaystyle \frac{35.5}{143.5}\times \frac{Weight \,of \, AgCl\times 100}{Weight\, of\, compound}$$

$$= \displaystyle \frac{35.5\times 0.574\times 100}{143.5\times 0.378}$$

$$= 37.57$$%

Hence, percentage of chlorine (in nearest integer) = $$38$$.
