A compound was found having nitrogen and oxygen in the ratio 28 gm and 80 gm respectively. The formula of the compound is_________________?
Correct answer: B. N2O5
- A. N2O4
- B. N2O5
- C. N2O3
- D. None of these
Explanation
The masses correspond to 28/14 = 2 gram-atoms of nitrogen and 80/16 = 5 gram-atoms of oxygen. The simplest whole-number ratio is therefore N₂O₅.
