For the reaction NH4NO2 (to) N2 + 2H2O, calculate the volume of nitrogen that would be produced at S. T. P from 3.2 g of the dioxonitrate(iii)salt. (Relative atomic masses: N = 14, O = 16, H = 1)

A.
2.24 dm 3 -
B.
2.24 cm3 -
C.
1. 123 -
D.
1. 12dm 3 -
E.
4. 48 dm 3
Correct Answer: Option D
Explanation
(NH_{4}NO_{2}) (to) (N_{2}) + (2H_{2}O)
(64g) (to) (22.4dm^{3})
(3.2g) will give (frac{22.4}{64}) (times) (frac{3.2}{64})
= (1.12dm^{3})
