Question

During estimation of nitrogen by Dumas’ method of compound X (0.42 g) ____ mL of N2 gas will be liberated at STP. (nearest integer) (Given molar mass in g mol−1 : C : 12, H : 1, N : 14) [Structure shown in the source page: a six-membered ring containing two NH groups opposite each other, i.e. piperazine-like structure with two NH units]

Accepted Answer

109. The Dumas method estimates nitrogen content based on the molecular structure of the compound, which contains two nitrogen atoms. Given the mass of the compound and its nitrogen content, the calculation shows that 0.42 g of the compound releases approximately 109 mL of nitrogen gas at STP.
