Question

Place the following gases in order of increasing density at STP. N₂ NH₃ N₂O₄ Kr A) N₂O₄ < Kr < N₂ < NH₃ B) Kr < N₂O₄ < N₂ < NH₃ C) N₂ < Kr < N₂O₄ < NH₃ D) NH₃ < N₂ < Kr < N₂O₄ E) Kr < N₂ < NH₃ < N₂O₄

Quizplus · Accepted Answer

Density at STP is proportional to molar mass. NH3 (17 g/mol) < N2 (28 g/mol) < Kr (84 g/mol) < N2O4 (92 g/mol).
