In a Carius estimation, $0.400 g$ of an organic chloro compound gave $0.574 g$ of $AgCl$ . Use atomic masses Ag = 108 and Cl = 35.5. The percentage of chlorine in the compound is (answer to two decimals)

Numerical answer type, answer in %, tolerance 0.02.

Answer: 35.5 %

Molar mass of

AgCl

= 143.5, so mass of Cl =

(35.5/143.5) \times 0.574 = 0.1420 g

. Percentage of Cl =

(0.1420/0.400) \times 100 = 35.50%

.
