In an estimation of bromine by Carius method,$1.6 \ g$ of an organic compound gave $1.88 \ g$ of $AgBr$. The mass percentage of bromine in the compound is..........
(Atomic mass,$Ag = 108, Br = 80 \ g \ mol^{-1}$)

$0.25 \ g$ of an organic compound containing chlorine gave $0.40 \ g$ of silver chloride in Carius estimation. The percentage of chlorine present in the compound is $.....$ [in nearest integer].
(Given: Molar mass of $Ag$ is $108 \ g \ mol^{-1}$ and that of $Cl$ is $35.5 \ g \ mol^{-1}$)

In the Carius method of estimation of halogen,$0.15 \ g$ of an organic compound gave $0.12 \ g$ of $AgBr$. Find out the percentage of bromine in the compound.

Match column $-I$ and column $-II$ with the correct relation:

Column $-I$	Column $-II$
$(i)$ Dumas method	$(a)$ Absorption of $NH_3$ in $H_2SO_4$
$(ii)$ Kjeldahl's method	$(b)$ $BaCl_2$ by added $BaSO_4$
$(iii)$ Carius method	$(c)$ Mixture of Magnesia
$(iv)$ Estimation of phosphorus	$(d)$ $N_2$

In the Carius method,$0.099 \, g$ of an organic compound gave $0.287 \, g$ of $AgCl$. The percentage of chlorine in the compound is:

In the Kjeldahl's method for estimation of nitrogen present in a soil sample,ammonia evolved from $0.75 \ g$ of sample neutralized $10 \ mL$ of $1 \ M \ H_2SO_4$. The percentage of nitrogen in the soil is (in $.33$)
