Consider the following reaction. On estimation of bromine in $1.00 \ g$ of $R$ using Carius method,the amount of $AgBr$ formed (in $g$) is . . . .
$\overline{[Given :}$ Atomic mass of $H = 1, C = 12, O = 16, P = 31, Br = 80, Ag = 108]$

In Dumas method for estimation of nitrogen, $0.50 \ g$ of an organic compound gave $70 \ mL$ of nitrogen collected at $300 \ K$ and $715 \ mm$ pressure. The percentage of nitrogen in the organic compound is . . . . . . $ \% $ (Aqueous tension at $300 \ K$ is $15 \ mm$).

Nitrogen present in an unknown organic compound was estimated by the Dumas method to be $17.7 \%$ by weight. The compound is very likely to be ....

Which one of the following methods can be used to find out the percentage composition of halogen present in an organic compound?

In $Duma's$ method for estimation of nitrogen,$0.25 \ g$ of an organic compound gave $40 \ mL$ of nitrogen collected at $300 \ K$ temperature and $725 \ mm$ pressure. If the aqueous tension at $300 \ K$ is $25 \ mm$,the percentage of nitrogen in the compound is:

While estimating the nitrogen present in an organic compound by Kjeldahl's method,the ammonia evolved from $0.25 \ g$ of the compound neutralized $2.5 \ mL$ of $2 \ M \ H_2SO_4$. The percentage of nitrogen present in the organic compound is $......$
