Q. Duma's method involves the determination of nitrogen content in the organic compound in the form of
A) $NH_{3}$
B) $N_{2}$
C) $NaCN$
D) $\left( NH_{4} \right)_{2}SO_{4}$
Explanation
(b)
Duma's method involve the determination of nitrogen content in the organic compound in the form of $N_{2}$
$N_{2}O + Cu \rightarrow N_{2} + Cu$
$d\%\ of\ N = \frac{28}{22400} \times \frac{volume\ of\ N_{2}at\ NTP}{weight\ of\ compound} \times 100$
